Frequency loop gain
0 to 100
33
Only with voltage / frequency ratio set on F or L
Enables adjustment of the speed controller’s
response time
- 0 to 33
: longer response time
- 33
: factory setting
- 33 to 100 : shorter response time
Applications:
- machines with high resistive torque or high
inertia adjust the frequency loop gain In the 0
to 33 zone.
- machines with fast cycles, low resistive torque
or low inertia adjust the gain In the 33 to 100
zone.
Precaution: excessive gain can lead to
unstable operation.

Adjust the skip frequencies 1 (and 2) on the
value (or values) read.
If resonance persists, widen the skip frequency
band from 2 to 5 Hz, see special function
