Parameters Description
5 PARAMETERS DESCRIPTION
The CFW11 inverter parameters (P0000 to P0999) and the SoftPLC function parameters (P1000 to P1059)
for the Solar Pump Drive application will be presented next.
NOTE!
The Solar Pump Drive application only works on CFW11 inverter with firmware version over
V6.10 So, upgrading the CFW11 inverter firmware to the working of this application is required.
NOTE!
The adjustable range of the CFW11 parameters has been customized for Solar Pump Drive
application. Refer to the CFW11 programming manual for more details on the parameters.

5.1 VOLTAGE REGULATOR
This group of parameters allows the user to configure the operating conditions of the voltage regulator for
operation by the photovoltaic modules, both for direct pumping and pressure regulation.
P1019 – Increment Rate MPPT
Adjustable 10 to 40
Range:
Properties:
Access groups via HMI:
Description:
This parameter defines the variation rate of voltage setpoint for maximum power point tracking. Initially leave
this parameter with the defect value and in case of Setpoint variation it is not fast enough to gradually increase
until the optimum operating result is achieved.
5.1.1 Voltage Setpoint Limits
P1022 – Minimum Setpoint Vdc
Adjustable 0 to 1000 V
Range:
Properties:
Access groups via HMI:
Description:
This parameter defines the minimum value of the voltage setpoint that the system must use during the
process of maximum power point search.
P1023 – Maximum Setpoint Vdc
Adjustable 0 to 1000 V
Range:
Properties:
Access groups via HMI:
Description:
This parameter defines the maximum value of the voltage setpoint that the system must use during the process
of maximum power point search.
