S0.07
Slip compensation Factory default 0.00
Setting
range
0.00...10.00 Hz Minimum unit 0.01
● Compensates the speed difference of the motor and the output of the
frequency converter caused by the load in case of V/F control so that
the rotor speed gets closer to that of the synchronous speed at its rated
load.
● Improves the mechanical behavior of the motor. Should be set accord‐
ing to the rated motor slip frequency shown on motor plate.
S0.08
Torque increase Factory default 0.1
Setting
range
0.0...20.0 % (of rated frequency con‐
verter voltage):
● 0.0 %: Automatic increase
● 0.1...20.0 %: Manual increase
Minimum unit 0.1
● 0.0 %: Automatic increase
Determines automatically the percentage of output voltage increase
based on output frequency and load current.
The linear and square V/F curve automatic torque increase are shown in fig‐
ures below.
