5.44.7 Aux Motor PID Compensation
When the number of operating auxiliary motors increases, the flow rate of the pipe also
increases and the pressure of the pipe line decreases. Aux motor PID compensation
compensates for this pressure when the number of the auxiliary motor increases. By adding
the additional PID reference value (relevant to the auxiliary motor) to the current reference,
the loss of pressure can be compensated for.

Comp
Set the relevant PID reference compensation rate whenever the auxiliary
motor is turned on. The PID reference can be set over 100%, but when it
exceeds 100%, the maximum value of the PID reference is limited to
100%.
