Parameters Description
P1038 – Cloud/Load Controller Activation Level
Adjustable 0.0 to 100.0
Range:
Properties:
Access groups via HMI:
Description:
This parameter defines the threshold percentage error value between the voltage SP and the DC Link
voltage for activating the Cloud/Load Controller.
P1038 – Cloud/Load Controller Gain
Adjustable 0.00 to 10.00
Range:
Properties:
Access groups via HMI:
Description:
This parameter defines the value of the Cloud/Load Controller gain that will be added to the DC Voltage PID
Controller actuation.
Adjust the level to enable the cloud/load effect controller (P1038) and the controller gain (P1039), gradually
increase the controller gain to a faster response.

5.1.3 System Start Configuration
This group of parameters allows the user to configure system start options.
P1027 – Time Between Starts
Adjustable 0 to 3600 s
Range:
Properties:
Access groups via HMI:
Description:
This parameter defines the time base between starts, when the system is stopped by power failure or the DC
Link reaches the minimum voltage limit (P1022).
During the starting process the system monitors the energy available on DC Bus, in case of insufficient energy
to accelerate the motor pump to the minimum speed, the system automatically recalculated the time between
starts, using the time base (P1027) as reference to a new start attempt (Figure 5.1). The remaining time to a
new start attempt can be monitored by P1016.
This delay is to avoid continuous starts and stops, and in the case of submersible pumps, preventing the restart
of the pump before emptying the pipe. The setting value of P1027 must be greater than the pump deceleration
time (P0101).
NOTE!
If the run command is removed from the system, the time will be reset and once go back to
operate the run command the start will be realized immediately without consider any time.
