Switching frequency
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.
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.
Unit: 1
Value range: 0 = switching frequency constantly 8 kHz
1 = 16kHz with automatic reduction
Default setting: 0
Adjusted value: as needed
i
Open loop torque boost
Unit: % of input voltage
Value range: 0.0...25.5 %
Default setting: 5.0 %
Adjustment value: dependent on load, adjust incrementally.
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 or too little boost can lead to high
current while running open loop.
