P3.13.6.5 RESPONSE TO PID SUPERVISION FAULT (ID 749)
Use this parameter to select the response of the drive to a 'PID Supervision' fault.
If the PID feedback value is not in the supervision limits for longer than the supervision delay,
a PID supervision fault occurs.
10.14.7 PRESSURE LOSS COMPENSATION
When you pressurise a long pipe that has many outlets, the best position for the sensor is in
the middle of the pipe (the position 2 in the figure). You can also put the sensor directly after
the pump. This gives the right pressure directly after the pump, but farther in the pipe, the
pressure drops with the flow.

P3.13.7.1 ENABLE SETPOINT 1 (ID 1189)
Use this parameter to enable the pressure loss compensation in the pump system.
In a pressure controlled system, this function compensates the pressure loss that occurs at
the end of the pipe line due to the liquid flow.
P3.13.7.2 SETPOINT 1 MAX COMPENSATION (ID 1190)
Use this parameter to set the maximum compensation for PID setpoint value that is applied
when the output frequency of the drive is at the maximum frequency.
The compensation value is added to the actual setpoint value as a function of the output
frequency.
Setpoint compensation = max compensation * (FreqOut-MinFreq)/(MaxFreq-MinFreq).
