Open Loop Torque Boost; Switching Frequency - KEB COMBIVERT F5 Instruction Manual

Parameter Description - Control Settings
Open loop torque boost
Switching frequency
Adjusts the torque boost only during open loop operation
(LF.30=0). If the torque boost is too low the motor may not be
able to lift the load. Too much boost can lead to high current
while running open loop.

Adjustment value:
Using parameter LF.38 the switching frequency of the inverter can
be set. The switching frequency can be constantly 8 kHz or 16kHz
with an automatic reduction based on the heat-sink temperature.
i
If the display often shows the error message E.OL2, then this
parameter should be set to zero. Some power stages only sup-
port 8Khz. On these units it is not possible to change to this
value.
