Set the boost compensation (%).
Setting "0" makes the automatic torque boost inoperative.
Normally set "100" (%) to make the automatic torque boost
operative
39
0
0 to 500
Set the automatic torque boost operation starting current (A).
Normally set "0" (A).
4.2.19 Up-to-frequency sensitivity (Pr. 41)
Pr. 41 "up-to-frequency sensitivity"
The ON range of the up-to-frequency signal (SU) output when the output frequency reaches the running
frequency can be adjusted between 0 and
±
100% of the running frequency.
This parameter can be used to ensure that the running frequency has been reached or used as the operation
start signal etc. for related equipment.
