1 Introduction
The H2P Series drives with Pump software have an Application Group (AP1) of parameters that includes
parameters to program the drive(s) to control multiple motors. Some of the multiple motor control functions included
are Lead/Lag (with Fixed Lag or Follow Lead), Alternation (FIFO & FILO settings), Staging and De-staging settings,
Run Priority (order) and Jockey Pump control. There is also a Macro Group of parameters (MC2 Group) that
includes parameters for quick setup. All Lead/Lag methods described below utilize PI Control requiring as a
minimum, the Lead drive to receive a feedback signal of the process variable (pressure, level, etc.). The MC2 Group
also includes setup of basic PI control parameters.
There are four (4) methods to control multiple motors. Each is described in more detail below. To view parameters
related to Lead/Lag, select “Lead Lag Sel” at the Quick Start menu or at parameter CNF-43. See Section 5,
Parameter Setup. This will open the AP1 Group and create the MC2 Macro Group which includes the majority of
Lead/Lag parameters required for quick setup.
The four (4) methods of multi-motor control are:
(1) Contactor Lag
(2) Follow Lead
(3) Fixed Lag
(4) Network Fbk
1.1 Lead/Lag Descriptions
•Contactor Lag - Utilizes one Main drive along with relay logic to control ATL contactors or starters (referred
to as AUX motors). A single drive can control up to five (5) AUX motors (8 with Ext. IO Card) via output
relays from the Main drive. The relays are programmed to add/remove additional (AUX) motors as needed.
This is for a single drive only, not multiple drives. Contactor Lag (MMC) operation is covered in a
supplemental manual that describes this method in more detail.
•Follow Lead - Utilizes one Main drive and Lag drives that operate at the same frequency (follow) as the
Main PI controlled drive. A Lead drive (designate by “+”) controls all communications to the Lag drives. A
Lead/Lag system can incorporate up to five (5) LAG drives (8 with Ext. IO Card). Follow Lead can be
operated with a single transducer to the Lead (+) drive or with feedback provided to all drives in the
Lead/Lag system.
•Fixed Lag - Utilizes one Main drive and Lag drives that operate at a set speed (fixed frequency). A
Lead drive (designate by “+”) controls all communications to the Lag drives. A lead/Lag system can
incorporate up to five (5) LAG drives (8 with Ext. IO Card). Fixed Lag can also be operated with a single
transducer to the Lead drive or with feedback provided to all drives in the Lead/Lag system.
•Network Feedback - Setting for Lag drives only that are not receiving a feedback signal. Lag drives operate
in accordance with Lead (+) drive setting (Follow Lead or Fixed Lag). Lag drives set to Network Feedback
cannot become a Lead (+) drive and thus a transducer connection is not required.

2 Lead/Lag Characteristics
2.1 Terminology and Definitions
◼Lead (+) Drive - The drive that controls communications of the entire system. Note the designation of
(“+”) for the Lead (+) drive. There is only one Lead (+) drive. The Lead (+) drive is a drive that receives
transducer feedback. The “+” designation is shown on the LCD display. See Section 3, LCD
Display/Keypad.
◼Main Drive - A drive that is performing the PI Control. There is only one Main drive. The Lead (+) drive
can be the Main drive, but when a 2nd drive is staged, the 2nd drive now takes over the PI Control and
becomes the Main drive. The PI Control is shifted from the Lead (+) to the Main drive. The Lead (+)
drive now becomes a Lag drive but still controls communications, but not PI Control.
◼Lag or Aux Drive - A drive that operates under the control of the Main drive. There can be up to 7
Lag (or AUX) drives as one is a Main drive.
2.2 Characteristics of Lead/Lag Operation
◼Each drive’s ID must be set differently with COM-01 (Int485 St ID).
◼Each motor/pump is connected to a drive. The Lead (+) drive controls communications of the entire
system. Note the designation of (“+”) on the LCD display of the Lead (+) drive.
◼Lag (or Aux) drives when staged become the Main PI controlled drive as they take over the PI Control
of the system. The PI Control shifts to each Lag (or Aux) drive making it the Main PI controlled drive.
The Lead (+) drive now becomes a Lag (or Aux) drive but retains the (+) for communications.
◼Lag (or Aux) drives are controlled based on Lead (+) drive operation (Follow Lead or Fixed Lag) and
the PI function of the Main drive.
◼A Lead/Lag system with only one transducer connected to one drive can only have one Lead (+) drive.
Lag drives are set to Network feedback.
◼A Lead/Lag system with each drive receiving feedback, the Lead (+) drive can change. Feedback can
be from individual transducers to each drive or from one transducer wired to all drives (series 4-20mA
loop).
◼If the Lead (+) drive is manually stopped, trips or malfunctions, a Lag (or Aux) drive takes over as the
Lead (+) drive and continuously controls the system. The Lag (or Aux) drive must be connected with
transducer (feedback) to become the Lead (+) drive.
◼A Lead/Lag system with each drive receiving feedback, the first drive to be put into AUTO state (button
on Keypad) becomes the Lead (+) drive.
◼A Lead/Lag system with each drive receiving feedback, when all drives are powered up at the same
time, the drive with the lowest ID (COM-01, Drive ID) becomes the Lead (+) drive.
◼Drives will power up to their last operating state. If in AUTO, will power up to Auto. If OFF, will power
up to Off.
◼Alternation (AP1-49) can be set to FILO, FIFO or based on operating time where the operating time
of each drive/motor/pump is evenly distributed.

3.3 HAND-OFF-AUTO Buttons - Operation
AUTO Button
Start-Stop control is from the AUTO button on the LCD display/keypad. A separate input to the P1 terminal
(Fx start command) is not required. The AUTO button will start and stop each of the drives.
Press
OFF -> AUTO (green LED blinking) -> AUTO again (green LED ON), drive is in Forward Run Mode.
See Section 3.4, Start/Stop Control for more details.
OFF Button
When stopped manually with the OFF button, the drive will decelerate and eventually go into stop mode (STP).
If the Lead (+) drive is stopped, Lag drive will become Lead (+) drive (status to F1+) with correct settings. The
stopped drive will not auto restart until Auto button is pressed again. The status display will change from STP
to F2 (or current priority) and restarts.
HAND Button
Caution - Pressing the HAND button on the LCD display/keypad will start the drive. In HAND mode,
operating frequency (speed) is set at the Monitor display (MON), Frequency is on Line-1 using the Up,
Down, Left and Right arrow buttons. The frequency (speed) displayed at the Monitor display (MON) is
duplicating parameter DRV-25, “HAND Cmd Freq”. The default speed is 0 Hz. The drive will ignore a
digital input for start/stop and will not be in PI Control Mode. If digital inputs are made for FWD JOG or
REV JOG, these override the DRV-25 (Hand Cmd Freq) frequency setting and operate based on DRV-11
(JOG Frequency), DRV-12 (JOG Acc Time) and DRV-13 (JOG Dec Time).
Note: When powered is cycled, the drive will reboot to the same status it was in before power was removed.
EX: If Stopped (via OFF button), will reboot to off mode. If in AUTO mode (Forward run mode) before power
was removed, it will reboot to AUTO, Forward run mode (AUTO LED green, not blinking).
3.4 Start/Stop Control
The Lead/Lag software default settings for start/stop are set to automatic. By pressing the Auto button once
on each drive, the drives will be in the ready mode (Auto LED blinking). Pressing the Auto button a second
time will start the drives. A separate start command at terminal P1 is not required.
This is based on the default setting of parameter IN-87 for the P1 Start terminal. Terminal P1 is set to
normally closed (first bit set to “1”). This was done to minimize wiring to each drive. Also related to
automatic start is parameter ADV-10, Power On Run. With ADV-10 set to “Yes” (default), this permits the
drive to automatically start on Power Up. When cycling power to the drives, they will return to the mode
(Auto, Stop, Hand) they were in prior to the power being cycled.
If a separate Start/Stop input at P1 is being used, change the setting of IN-87 to all zero’s (0).

4 Transducer and Communications Wiring
The below connection diagrams show wiring for a 2 pump (duplex) system using a single transducer
connected to a single drive and also a single transducer connected to multiple drives (4-20mA Loop).
Alternately, a separate transducer can be connected to each drive.
The difference between the two diagrams is; with a single transducer to a single drive, the Lag drives
cannot become a Lead (+) drive if the Lead (+) drive is manually stopped, trips or malfunctions. A Lag drive
must receive a feedback signal (4-20mA Loop or separate) to become a Lead (+) drive for continuous
control of the system. Depending on transducer wiring, see Note in Section 6, Macro 2 Group (MC2) for
parameter MC2-03 setting for Lag drives.
Utilize the standard H2 Drive Manual for wiring not related to the Lead/Lag operation (any additional I/O for
control and monitoring). Note the communications connection among all drives (S+ to S+ and S- to S-) and
verify the polarity is correct for communications.
Important: Turn ON the terminating
resistor on the last drive in the network.

5 Parameter Setup
Follow the steps below to setup H2P drives to operate as a Lead/Lag system. The H2 Pump Software (H2P) has a
macro group of parameters (MC2 Group) that includes settings for multiple drive / multiple motor control. The MC2
Group includes parameters from other groups, including AP1 Group, PID Group and others. The MC2 Group
parameter list and settings are shown in the table in Section 6, Macro 2 Group (MC2).
Step 1: Upon Power Up, at Run QuickStart, select “Yes”.
Step 2: At 43 Macro Select, select (2) Lead Lag Sel.
Step 3: Set the remaining parameters within the Quick Start menu.
Step 4: Set a unique communication address at parameter COM-01 (Drive ID) in each drive.
•VFD#1 - COM-01 to “1”
•VFD#2 - COM-01 to “2”
Step 5: Cycle power after setting the above parameters.
Note: The default for COM-01 (Drive ID) is “0”. If COM-01 is not set in each drive, the drive will flash a warning
“Int485 St ID” as a reminder to set COM-01 when changing other parameters.
The firmware places the Lead/Lag parameters in a Macro group (MC2). To access the Macro group:
Step 6: At the first drive with COM-01 set as Drive ID 1, press the MODE button while viewing the upper left
corner of the LCD. Stop when U&M MC2 (User & Macro) is displayed. Set parameters in the MC2 Group. The
Macro group (MC2) includes parameters for Lead/Lag setup and are listed in the table in Section 6, Macro 2
Group (MC2).
•Data Share: When setting parameters in Drive #1, parameter’s designated as “Yes” in the Data
Share column of the parameter table will be changed in all Lag drives in the system. Note that the
Lead (+) drive must be in the Ready Mode (AUTO LED blinking) to Data Share. See Section
20, Data Share. Alternatively, if it is necessary to set or change a specific data shared parameter in
a Lag drive, change it within the Lag drive.

6 Macro 2 Group (MC2)
This table lists parameters in the macro group (MC2). It includes the MC2 group parameter number cross referenced
to the original drive parameter along with default settings for Lead/Lag operation. The Notes provide a brief
description of the parameter settings. For detailed descriptions of the parameters, refer to Section 8, Application
Group 1, AP1 Parameter Descriptions.
NOTE: For Lag drives only. Parameter MC2-03.
If using a single transducer to the Lead (+) drive only, set Lag drives to Network Feedback. If all drives are receiving
the transducer feedback signal, set Lag drives to same as the Lead (+) drive (Follow Lead or Fixed Lag).

8 Application Group 1, AP1 Parameter Descriptions
Parameter
Description
AP1-20
Soft Fill Sel
•No - Disables Pre-PID and Soft Fill
•Yes - There are two separate operations. Setting AP1-20 to "Yes" enables both Pre-PID and Soft Fill
operations.
▪First: Pre-PID based on AP1-21 (Pre-PID Frequency) and AP1-22 (Pre-PID Delay Time). The drive will
simply ramp to the AP1-21 Frequency and remain there for the AP1-22 Time. If the feedback
pressure goes above the AP1-23 (Soft Fill Set) amount, drive will exit Pre-PID and go into normal PI
operation.
▪Second: Soft Fill operation automatically changes the PI Reference (setpoint) set in PID-10 and PID-
11 to a "Soft Fill" PI Reference (setpoint). The Soft Fill PI Reference performs a series of steps that
increase over time to slowly fill a piping system. The steps are defined by parameters AP1-23, AP1-
24 and AP1-25.
AP1-21
Pre-PID Freq
•The drive will ramp up to the set Pre-PID frequency. It will remain there for the Delay time AP1-22 (Pre-
PID Delay Time) then go into Normal PI Control. If the feedback exceeds the amount set in AP1-23 (Soft
Fill Set) before the delay time, the drive will exit Pre-PID and go into Normal PI operation.
AP1-22
Pre-PID Delay
•Time to operate in Pre-PID mode at frequency set in AP1-21 (Pre-PID Freq).
AP1-23
Soft Fill Set
•When feedback reaches this PSI amount (or other PID Units) at any time during Pre-PID or Soft Fill, the
drive exits the operation and goes into normal PI operation. If drive was in the Soft Fill operation, the PI
Ref (setpoint) resorts back to the setpoint value (PID-11) instead of the Steps defined in AP1-24 and AP1-
25.
AP1-24
Fill Step Set
•After Pre-PID operation time, if feedback has not reached the AP1-23 (Soft Fill Set) exit amount, the PI
Reference (setpoint) will automatically change to this setpoint AP1-24 (Soft Fill PI Reference) amount and
start the Soft Fill operation. The "Soft Fill PI Reference" becomes the new PI setpoint. Soft Fill steps are
based on AP1-24 and AP1-25.
AP1-25
Fill Step Time
•This is the time of each step AP1-24 (Soft Fill Set). The step will increase by the AP1-24 amount when the
feedback reaches the Fill Feedback Difference (AP1-26). If the feedback remains below the Soft Fill Set,
the drive does not increase to the next step.
AP1-26
Fill Fdb Diff
•This is the difference between the Soft Fill Set PI Reference (AP1-24) amount and the feedback pressure.
When the feedback increases to the AP1-26 amount below the step amount (whichever step it is on), the
drive increases the Soft Fill Set PI Ref. to the next step. If the feedback remains below the AP1-26 amount,
the Soft Fill PI Ref. does not increase to the next step.
AP1-30
Flow Comp Sel
•No - Disables Flow Compensation operation.
•Yes - Enables Flow Compensation
▪Compensates for pressure loss due to long pipes and/or higher flow rates. The maximum amount of
compensation is set in AP1-31.
AP1-31
Max Comp Value
•The maximum compensation amount (PID Units) that is added to the PID-11 (PID Ref 1 Set) setpoint. The
compensation amount varies based on the follow:
•
AP1-40 / MC2-03
Lead Lag Sel
•Selecting MMC or Lead/Lag operation.
▪Contactor Lag: MMC operation.
▪Follow Lead: This is a Lead/Lag control method with one PID-controlled Main drive and all of the Lag
drives operate at the same frequency as the Main drive. Drives with this setting can become a Lead
(+) drive but must also have feedback connected. See Section 9, Lead/Lag - Follow Lead.

890053-02-00
Page 15 of 40
Parameter
Description
▪Fixed Lag: This is a Lead/Lag control method with one PID-controlled Main drive and all of the Lag
drives operate at a fixed frequency. See parameter AP1-60, Lag Freq. Drives with this setting can
become a leader drive but must also have PID feedback connected. See Section 10, Lead/Lag - Fixed
Lag
▪Network Fbk: For Lag drives only. A method of operation for all Lag drives that operate in accordance
with the Lead (+) drive setting of Follow Lead or Fixed Lag. A drive with this setting cannot be a Lead
(+) drive and thus a feedback connection is not required.
AP1-41
Regular Bypass
•For MMC (Contactor Lag) control only.
▪Regular bypass mode is a function that disables the PI Control and drive/motor speed is based on
the feedback signal.
▪Not used with Follow Lead, Fixed Lag or Network Feedback.
AP1-42 / MC2-07
* of Pumps
•For MMC, (Contactor Lag)
▪Sets the number of AUX Motors to operate with MMC
•For Follow Lead, Fixed Lag
▪Sets the total number of drives/pumps connected to the Lead/Lag system. This number may be
higher than the number of drives that are actually operated by lead/lag operation. See AP1-94 (* Of
Drives). If AP1-42 is set higher the AP1-94, the remaining drives become standby drives. Standby
drives can become part of the alternation sequence.
See Section 17, Standby
•For Network Fbk
▪The parameter is not used.

Lead Lag Status
(View Only)
⚫For MMC (Contactor Lag)
◼The parameter is not used.
⚫For Follow Lead, Fixed Lag, Network Fbk
◼It displays current Lead/Lag operation status of the specific drive (Trip, Manual, Interlock, Standby,
Sleep, Stop, Ready, Proc PID or Constant).
AP1-48 / MC2-23
Lag Stop Sel
⚫Sets whether to stop all drives (motors) simultaneously when the start/run command is removed from
the Lead (+) drive.
⚫If “No”
◼When the start/run command is removed from Lead (+) drive, it stops based on delay time AP1- 54
(Destage DT) and becomes standby drive (“F0” status). Lag drive can become Lead (+) drive and
operation can continue. With next start of standby drive (showing “F0”), it becomes Lag drive.
⚫If “Yes”
◼When the start/run command is removed from Lead (+) drive, all drives/motors are stopped
simultaneously.
⚫For Network Fbk
◼The parameter is not used.
AP1-49 / MC2-04
ALT Sequence
⚫Sets the operating sequence.
⚫For MMC (Contactor Lag), Fixed Lag and Follow Lead
⚫FILO (First In Last Out)
◼Stops in the reverse order in which motors were started. When motors start in the order of 1-2-3-
4, they stop in the order of 4-3-2-1.
⚫FIFO (First In First Out)
◼Stops in the same order in which motors were started. When motors start in the order of 1-2-3-4,
they stop in the order of 1-2-3-4.
⚫Op Time Order
◼The sequence is automatically determined according to the operation time of each drive/motor.
◼Example: When Motor 1,2,3,4 (Drive ID’s 1,2,3,4) operation time is 6h, 9h, 8h, 7h, the operating
sequence will be Motor (Drive ID) 1-4-3-2, and they will stop in the order of 2-3-4-1.
⚫For Network Fbk
◼The parameter is not used.
AP1-50 / MC2-11
Stage Pres. Dv
⚫One of the conditions for Lag drive (or Aux) to operate (stage). It is the difference between the PID
feedback and the PID reference (setpoint). Above or below setpoint is based on PID-36 (PID Output
Inverse) setting.
◼For PID-36 set to “No” (normal PID), it is deviation below setpoint.
◼For PID-36 set to “Yes” (Inverse PID), it is deviation above setpoint.
⚫For Network Fbk
◼The parameter is not used.
