F1.13 Compensate for slip freq.
Setting range： 0.0 ~ 150（％）
The actual slip of motor will change with the load change. The inverter, through setting of this functional parameter,
will automatically regulate its output frequency according to the load condition to compensate the influence of the load
on motor speed. This parameter is only valid for V/F control mode.

Droop control is a special control mode to poise output power when multi-inverters inverter the same load or rotator
speed of motor will change with the load. It will poise power and torque by setting those parameters, when
multi-inverters inverter the same load. If those parameters are appropriate set, applied asynchronous motor will have
the same characteristic with torque motor. Shown as fig6-9.
