Pump Control Quick Guide 4
The target of a pressure control system is to provide a variable flow with a constant pressure for the water
system of an apartment building, machine refrigeration systems, mixing liquids in chemical industry, etc.
A very typical example is providing the water supply for a residential building. In this case, the flow
(water consumption) is greater in the morning than during the night (when it’s almost non-existent) The
pressure control system must be able to provide, at the same pressure, both types of consumption
(Daytimehigher flow, and during the night almost no flow); in addition, the system has to adapt to the
demand variations that occur normally in this kind of application, for example, when people turn taps on
and off at the same time.
The inverter has been designed to fulfil all the requirements of the different pump control
systems. Some of its more important functions are:
•Stop function due to low water flow (Sleep Function)
•Start-up function because of water demand (Wake-up Function)
•Software limits (current, voltage and frequency) to protect the motor and the pump
•Control of multiple pumps on 1 regulated pump + auxiliary pumps topology (Mono-regulated
pump Control)
•Control of multiple pumps on multi regulated pumps topology (Multi-regulated pump Control)
•Possibility to add an additional pump (FDT Function) to both topologies
•Many functions to avoid overpressure and water losses (Warnings, alarms, etc.)
•Possibility of exact adjustment of the levels for start-up and stop of the auxiliary pumps to fine
tune system behaviour.
•Possibility of the exact adjustment of the levels to start-up and stop of the PID control, during the
connection/disconnection of the auxiliary pumps, to fine tune system behaviour
•Independent ramps for the start-up and the stop of the regulated pump, separate from the
ramps for the connection/disconnection of auxiliary pumps
•Selection of the sequence for the pumps’ activation/deactivation
•Sequenced switching rotation of the pumps (by timer or intelligent control)
•Possibility of sharing the working time between the pumps
•Information about the working time of each pump
•Pressure sensor disconnection detection
•Selecting different warnings (low-pressure, overpressure, etc.)
•Protective function to protect pump from the absence of water (Dry well function)
•“By-pass” sequence integrated
•Control of the delay time between connection and disconnection of the contactors
•Display units and sensor range adjustments
•Selectable ‘Pump Stop’ Strategy?
•Multiple frequency command selection (by means of digital inputs)
•Dew condensation prevention Function
•Safe energy Functions
Regulation by means of PID control:
A PID control is a regulation system involving the set value (SV - desired pressure) and a process value
(PV - Feedback, measure of real pressure or flow from a transducer). From these two values the
difference, or error, is calculated, subtracting one from the other. The PID control then adjusts its output
demand (MV - pump’s speed) in order to minimize the error:
-If the error is positive (desired pressure greater than real pressure) speed should increase
-If the error is negative (desired pressure lower than the real pressure) speed should decrease
-If the error is zero (desired pressure equal to real pressure) speed should stay at the same level
Parameters (gains) to adjust: Proportional, Integral and Derivative components (though Derivative
component is not normally used in this application) help to select how quickly the system will respond to
pressure and consumption changes. Normally, a quick (dynamic) response is desired, but pressure peaks
and oscillations must be avoided.

When a regulated pump is being controlled, it’s necessary to consider certain parameters in order to allow
the inverter to control the pump’s start-up and stop, controlling speed to maintain the desired pressure,
etc.
The schematic to implement control by only 1 pump by means of inverter, is as follows:

Figure 1.1: control schematic for 1 pump only
By means of the keypad, a digital input or an analog set point, the desired pressure can be selected. Once
this pressure is set, inverter will modify pump’s speed between a minimum (J19 = F16 (Hz)) and a
maximum (J18=F15=F03 (Hz)) frequencies, in order to stabilize the pressure.
To work in this way, the integrated PID control must be enabled (J01) and adjusted properly. Then, the
inverter’s response should be the required action to control the application.
PID’s response can be modified by means of parameters J03 and J04 (Proportional gain and Integral time).

Pump Control Quick Guide 7
When the “RUN” signal is switched on (either FWD or R V), the inverter will increase the output frequency
(always after the period time defined in J38 (sec)). In order to control this rising output, some parameters
are available: F23 (Hz) controls the starting frequency, J43 the starting PID frequency and the ramp from
one to the other (F07) (sec.). Once J43 frequency level is achieved, PID control is enabled. In the same
way, when the “RUN” signal is switched off, the inverter decrease its output frequency to the level defined
in F25 (Hz) (the deceleration time is set in F08 (sec)), and stops the PID control.
Sleep Function (related parameters: J15 (Hz), J1 (sec.))
Sleep function can be useful to stop one pump when the speed is below a rate where there is no flow
(pump doesn’t impel).
Once the demand frequency level is below this rate (the frequency when the pump begins to move the
water but not enough to create a flow) is known, parameter J15 (Hz) should be set slightly higher than
this frequency.
Through this function, is possible to avoid possible mechanical problems that could (over time) damage
pump components or ‘boil’ the water with the wasted energy causing excess pressure and leaks. In
addition, stopping the pump when it’s not really needed means, obviously, nergy Saving.
So, Sleep Function will be applied if the inverter’s demand output frequency is lower than the ‘sleep’ level
stored in parameter J15 (Hz) and it stays at a lower level for a time longer than that specified in J16 (sec).
In Figure 1.2 sleep function is shown. The deceleration time to get to the “Stop Frequency” is stored in
F08 (sec.).
Important: Sleep frequency (J15 (Hz)) must be lower than the wake-up frequency (J17 (Hz)) and must be
higher than the minimum frequency (F16=J19)
Wake-up function (related parameters J17 (Hz), J23 (%), J24 (sec))
Wake-up function is useful to start-up a pump again that previously was stopped by the sleep function.
In order to wake up a pump, 3 conditions must be accomplished:
MV ≥ J17 (Hz)
|SV – PV|≥ J23 (%) (*) Delay Time ≥ J24
(sec)
Manipulated value (MV,
PID’s output) must be
greater than the level
stored in J17 (the current
MV value can be ridden
from 3. OPR MNTR
inverter’s menu.)
and...
The absolute value of the process error
(the subtraction between the process
value and the set point value ) must be
greater than the percentage in J23
and...
Both conditions must be
met for longer than the
time specified in J24
(*) J23 is related with 40 and 41 function codes as follows: (|SV – PV|) / (E40 – E41) ≥ J23 (%) , ( 40
and 41 explained on page 42).
As the three conditions have to be met in order for the pump to start, multiple start-ups due to pipe losses
can be avoided. So, we avoid waking up the pump unnecessarily or too often.
In figure 1.2 is shown how the pump wakes up when accomplishes the three conditions.
Important: Sleep frequency (J15 (Hz)) must be lower than the wake-up frequency (J17 (Hz)).
In addition, sleep frequency must be higher than minimum frequency (F16=J19)

COMMON PARAMETERS DESCRIPTION
Basic Function
F02: Run Command
This function code defines the way in what the “RUN” signal will be given to the inverter in order to start
the pressure control.
Usually, “Run Command” is sent to the inverter by means of the digital input (F02 = 1). That is, switching
on FWD or R V (control terminals in the inverter) digital inputs enables the inverter output.
A RUN command can be also activated by means of the keypad, pushing FWD or R V buttons (in TP-G1
keypad) or RUN in basic keypad (TP- 1).
F07: Acceleration Time 1
F08: Deceleration Time 1
These acceleration/deceleration ramps are used in two cases:
1. After the Run Command is ON, F07 ramp is used to achieve the frequency in J43 or J19 (the
biggest one of both values).
When the Run Command is switched OFF, F08 value defines the deceleration ramp to go from the
current frequency to the stop frequency (F25).
2. These ramps are also used when the inverter is connected/disconnected from the commercial
power supply if function codes J39 and J40 are set to 0.00 (please refer to the corresponding
diagrams in the following chapters).
F11: lectronic Thermal Overload Protection. Overload detection level
F12: lectronic Thermal Overload Protection. Thermal time constant
By means of these two parameters is possible to adjust the overload protection function. Normally, F11
will be adjusted to the motor’s rated current and F12 to 5 minutes.
F15: Frequency Limiter. High
F16: Frequency Limiter. Low
These two parameters define the frequency limits, and the inverter will never go outside of these limits
during pump control.
It’s normal to adjust the parameters F15, J18 and F03 with the same value.
qually, F16 should be equal to J19, too.
Inputs Set-up
62: Analog Input for [C1]
This parameter can be used to select the function for analog input C1.
Usually this parameter is set to 62 = 5, this setting will define the [C1] analog input as PID Feedback
(pressure transducer).
Motor Map
P01: Motor. Number of poles
P02: Motor. Rated Capacity
P03: Motor. Rated Current
In these parameters must be stored the number of poles, rated capacity and rated current as are shown in
the motor’s nameplate.

Pump Control Quick Guide 11
Special Functions
H91: C1 Signal disconnection Detection
Disconnection of pressure sensor (cable failure).
When a value is stored in parameter H91 (between 0.1 and 60.0 seconds) the inverter will generate an
alarm (CoF) when it notices that C1 signal current is missing (C1 current < 2mA) during a time longer
than the value in H91.
H91 = 0  function disabled.
H91 ≠ 0  function enabled.
PID and pump control
J01: PID control. Mode selection
When J01 = 1 and the error between Set Point and Process Value is positive (SP - PV > 0), the PID
controller makes a positive output action control (MV > 0).
Alternatively, if J01 = 2 and the error between Set Point and Process Value is negative (SP – PV < 0) the
PID controller still makes a positive output action control (MV > 0).
J03: PID Control. P Gain
This parameter is used to set the PID controller’s proportional gain (P). This parameter must be adjusted
as it is needed on every application.
A high P value produces a PID controller’s quick response. Otherwise, a low P-value produces a slow
response.
J04: PID Control. Integral Time I
This parameter is used to adjust PID’s integral time (I). This parameter must be adjusted as it is needed
on every application.
A high integral time value produces a PID slow response. Otherwise, a low I value produces a quicker
response.
J18: PID control. Upper limit of PID process output
J19: PID control. Lower limit of PID process output
These parameters specify upper and lower limit process output values.
We set J18 = F15 = F03 and J19 = F16.

Pump Control Quick Guide 16
Mono-regulated pump control involves a pump exclusively driven by the inverter and other(s) pump(s),
working in “On-Off control” mode and directly connected to the commercial power supply.
The inverter will connect/disconnect the auxiliary pump(s) to the commercial power supply, in order to
achieve the desired pressure.
By means of the keypad, digital input or analog command, the desired system pressure will be set. Then,
the inverter will modify the speed of the regulated pump between the minimum frequency (J19 = F16)
and a maximum frequency (J18 = F15 = F03), keeping the pressure under control.
The inverter’s PID control must be activated (J01) and adjusted accordingly, ensuring the inverter’s
response is what the installation requires all the time.
PID control action can be adjusted by means of function codes J03 and J04 (proportional gain and integral
time).
Connection/Disconnection of an auxiliary pump is shown in Figure 2.5, with all the related function codes.

Pump Control Quick Guide 17
In the following, the requirements or conditions to activate an auxiliary pump are shown:
•Connection of an auxiliary pump
If the regulated pump’s output frequency is higher than the level established by J34 during the time
specified in J35, the inverter will understand that using the regulated pump is not enough to maintain the
required pressure, and the inverter is ready to connect an auxiliary pump to the commercial power supply.
When the condition above is accomplished, the inverter will decrease the output frequency of the
regulated pump to the value stored in J93, by means of the deceleration ramp in J39. Once the frequency
level J93 is achieved, the PID controller will be activated again.
The frequency level when the auxiliary pumps are connected is defined in function code J44.

In the following the requirements or conditions to deactivate an auxiliary pump are shown:
•Disconnection of an auxiliary pump
If the output frequency level of the regulated pump gets lower than the value stored in J36 during a time
longer than J37, the inverter will understand that the auxiliary pump is no longer needed and will begin a
disconnection process.
If the condition above is accomplished, the inverter will increase the output frequency of the regulated
pump until the frequency level specified by function code J94, by means of the acceleration ramp J40.
The frequency level when the auxiliary pumps are disconnected is defined by function code J41.

Pump Control Quick Guide 19
The following table (Table 2.1), “Common parameters to all the pump control systems”, shows the
common parameters to all of the control systems using inverter. These are known as the
basic parameters.
In addition to the following table, there is also a specific parameters table.
If you are adjusting the inverter by means of the TP- 1 keypad, it is recommended to set 52 to “2”, in
order to be able to access to all of the inverter’s menus.
Note: The following values are shown as an example and may not necessarily work in your application

Note: The default setting for function code J93 and J94 (0 Hz) may work properly in your installation
without adjusting it to the suggested value (40 Hz and 39 Hz respectively).
DESCRIPTION OF THE SPECIFIC FUNCTION CODES FOR MONO-REGULATED PUMP
CONTROL
Outputs Set-up
20, 21, 24, 27: Signal status assignment to Y1, Y2, Y5A/C, 30A/B/C
Function codes 20, 21, 24 and 27 define the function that will be assigned to terminals Y1, Y2, Y5A/C,
30A/B/C, respectively.
In a mono-regulated pump control system these outputs must be set in order to connect / disconnect the
auxiliary pumps to the commercial power supply (functions 61: pump 1 to commercial power supply, 63:
pump 2 to the commercial power supply, 65: pump 3 to commercial power supply and 67 pump 4 to
commercial power supply).
