PID Quick Start Guide for Fan and Pump Applications
PID is a control method that can be used for the purpose of automatically regulating flow or
pressure in fan and pump applications. Following steps 1 through 13 listed below in this guide will
simplify the start up of the MA7200 PLUS Inverter series for fan and pump applications using PID
control. Some of the steps are specific to pump applications only and will be so noted. The guide is
not intended to replace the MA7200 PLUS Installation and Operation Manual, and the user is urged
review this manual.
The PID method of control covered by this guide will consist basically of a set-point (operating point,
e.g. flow, pressure etc.) entered through the keypad and an analog transducer feedback signal (0 –
10 VDC or 4 - 20 mA). These two signals are then compared, and through PID processing, correct for
any load or environmental changes to maintain the set-point. Only the (P) proportional and (I)
integral parameters will be set and adjusted through the keypad to optimize performance. The
parameter (D) derivative will not be discussed or used in this guide as the factory setting is usually
sufficient for fan and pump applications. Actual values will be used to provide a realistic example of
setting up PID control.
Although the inverter can be controlled via serial communication, it is beyond the scope of this guide
and the user is referred to the MA7200 PLUS Installation and Operating Manual for further
information on this subject.
Step 1 – Before starting the inverter –Safety First!
Step 2 – Apply power to the drive.
Step 3 – Set drive to run mode.
Step 4 – Check fan or pump motor operation.
Step 5 – Making external digital input / output and analog feedback control wiring connections.
Step 6 – Select stop / start method of control.
Step 7 – Setting minimum speed in pump applications. (Pump applications only)
Step 8 – Select PID control and feedback input
Step 9 – Select engineering units.
Step 10 – Setting PID parameters
Step 11 – Setting acceleration and deceleration. (Note 1)
Step 12 – Setting PID sleep functions. (Pump applications only)
Step 13 – Testing the system.
Note 1 – The acceleration and deceleration parameters are not specific to PID control but are
included as part of the PID set-up.
SAFETY FIRST!
Step 1 - Before Starting the Inverter
• Referring to the MA7200 PLUS Instruction Manual, please review and verify that the correct
inverter size for the motor was received free of damage. To ensure personnel safety and to avoid
equipment damage, follow the precautions and the installation procedures for mounting, wiring,
and operating environment.
CAUTION - To avoid damage to the inverter when removing the inverter cover
and/or LCD Operator, refer to Appendix B for the proper procedure.
• In accordance with applicable codes make electrical connections to the motor and input power
terminals. (Refer to the block diagram, Fig. 4). No other external connections should be made at
this time, as the initial control will be from the keypad.

Step 2 - Apply Power to the Drive
• Apply AC power to the Inverter and observe the LCD Display Line 1; it should read
“Freq. Cmd 000.00Hz”. Line 2 should read “TECO”. The red LED on the STOP key should be on.
The DRIVE and FWD LED’s should be on. (See Fig. 1 below)
Step 3 - Set Drive to Run Mode
• If the red DRIVE LED is not on with AC power up, press the PGRM / DRIVE key until the red
Drive LED is on. The Inverter is now in the RUN mode.
Step 4 - Check Fan or Pump Motor Operation
•Enter 10.00Hz for the frequency reference and set parameter Sn-08 = 1 to disable Reverse
Direction Operation. Note: The output from the inverter is displayed in Hz as factory default. If
desired, the output may be displayed in other units such as (%) of full speed, PSI etc. (see
Step 9)

•Press the RUN key, and check the fan or pump direction of rotation. If the direction is not correct,
press the STOP key and wait until the fan or pump has come to a complete STOP. Next, power
down the inverter.
Danger
After the power has been turned OFF, wait at least 5 minutes until the charge
indicator extinguishes completely before touching any wiring, circuit boards or
components.
•Reverse any two of the fan or pump motor connections at the inverter ( U(T1),V(T2), or W(T3) ).
Next, following STEP 2, power-up the inverter; the motor direction should now be correct.
Step 5 – Making External Digital Input/Output and Analog Feedback
Control wiring Connections
•Before removing any covers or making any external control connections, power down the
inverter.
Danger
After the power has been turned OFF, wait at least 5 minutes until the charge
indicator extinguishes completely before touching any wiring, circuit boards, or

Step 6 – Select Start / Stop Method of Control (Sn-04)
•Before selecting this parameter, ensure the inverter is in the STOP mode.
•The set-point is selected by the keypad (Sn-05=0), and the start / stop method can be from the
keypad or external contact (see Fig. 2a). NOTE: The set-point can also be set from an external
source but commonly it is set from the keypad.
•The parameter (Sn – 04) is set to = 0 (keypad), as factory default. If external contact is desired,
follow the navigation procedure below to set (Sn-04 = 1).

Step 7 – Setting Minimum Speed in Pump Applications
(NOTE: In the case of a fan application skip this step and go to Step 8)
•In the case of pump applications it is normally required to limit the minimum speed that the
pump will operate regardless of the input speed command. The pump minimum speed is
usually specified either by the pump manufacturer or the application. Once this value has
been established, the minimum output frequency of the inverter and thus the minimum
motor (pump) speed can be set by parameter Cn-19. This parameter sets the minimum
inverter frequency output, and thus a minimum motor (pump) speed to a percentage of the
maximum output command frequency.
•The following is an example of setting the minimum motor (pump) speed to 1800 RPM,
which is 50% of the maximum pump speed, 3600 RPM.

Step 9 – Select Feedback Engineering Units (P1-01) and Scaling (P1-02)
•Initially the display will read output frequency in (Hz) as the factory default and is set by
parameter (Cn-28=0). If (Cn-28) is changed to (=1), then the display will read out in (%). The
setting of (Cn-28) is only valid if (P1-01=0), which is the factory default. Other engineering units
may be selected by parameter setting (P1-01) as described on the following page.
•In this step, the feedback engineering units that the system is controlling such as CPM in fan
applications or PSI in the case of pumps can be selected by parameter (P1-01). (See Appendix
Afor additional selections). The maximum value that the engineering units will be in any given
application is set by parameter (P1-02). These selections will now be displayed on the digital
operator.
Example: A pump application that has a feeedback transducer with a maximum value of
200 PSI i.e 200 PSI = 20mA or 10 Vdc, can be set as shown next.

Step 10 – Setting PID Parameters; Proportional Gain (Bn-17) and
Integral Time (Bn-18)
•After all external connections have been made and the protective covers have been
replaced, power up the inverter but do not run at this point.
•Parameters Bn-17 = 1.0 (Proportional Gain) and Bn-18 = 10.0s (Integral Time) are factory
set to the values shown. However, a good starting point for these values is setting the
Proportional Gain Bn-17 = 2.0 and the Integral Time Bn-18 = 5.0s. To change these
parameters, follow the keypad navigation procedure below.

Step 11 – Setting parameters acceleration (Bn-01) and deceleration (Bn-02)
times
•Acceleration and Deceleration times as well as the PID control [(P) Proportional Gain
and/or the (I) Integral Time (see STEP 11) directly control the system dynamic response.
The longer the acceleration and deceleration time, the slower the system response, and the
shorter time, the faster the response. An excessive amount of time can result in sluggish
system performance while too short of a time may result in system instability.
The starting values suggested by this guide normally result in good system performance for
the majority of fan and pump applications. If the values need to be adjusted, caution
should be exercised, and the changes should be in small increments to avoid system
instability.
•Parameters Bn-01 (Acceleration) and Bn-02 (Deceleration) are both set at the factory for
10.0 seconds. For fan and pump applications, the recommended starting values are 30
seconds. To change these parameters, follow the keypad navigation procedure as shown
next.

Step 12 – Setting PID Sleep Function parameters (P1-04), (P2-01),
(P2-02), (P2-03) and (P2-04).
(NOTE: In the case of a Fan application skip this step and go to Step13)
•The PID Sleep function is turned on by parameter (P1-04) when set to (=1). This allows the
system to turn off the PID and thus the inverter output so that the pump does not run when
the system level (PSI) is above the set-point. This sleep start level is set by parameter (P2-
01) in a range from 0 – 100% of the maximum inverter output. When the system level drops
below a value (the units are selected by Step 8) set by parameter (P2-03), the sleep
wakeup level, the output of the inverter will turn on. Parameters (P2-02) and (P2-04)
provide delay times in seconds for sleep start level and sleep wakeup level respectively.
Fig. 4 will serve to illustrate this.

•To further cover the PID Sleep function, the following is an example of the various
parameter settings that could be used. In this example the system will have the following
specifications:
- Max. Pump Motor Speed : 3600 RPM.
- Set Point: 150 PSI.
- Feedback Transducer Range: 0 – 200 PSI.
- Pump System Sleep Level: 2160RPM or 60% of max. speed set by
(P21-01=060.00). Sleep Level Delay Time: 10 sec. set by (P2-02=010.0 ).
- Pump System Wakeup Level: 100 PSI set by (P2-03=0100). Wakeup Time: 5 sec.
set by (P2-04=005.0).
•Referring to Step 9, set the engineering units to PSI (P1-01=02) and then the range to 200
(P1-02=0200).
•On the following pages the keypad navigation sequence is shown in setting the PID
parameters.
NOTE: The inverter must be in the Stop mode in order to turn on the sleep function.
