Operating Instructions
Cause
High load torques may cause error messages due to
overvoltage.
For an asynchronous motor, switch to sensor-less
control according to V/f characteristic (set P30 to
110).
Reduce switching frequency (P400).
Install input filter.
Install output filter.
Connect motor and frequency inverter to PE poten-
tial.
Install mains and motor cables separately from the
control cables.
Avoid motor vibration.
Set blocking frequencies (P447, P448) and hysteresis
(P449) to disable output frequency ranges.
Set P475 or P492 to "30 - Technology controller".
Set P476 or P494 to the source for the reference
value.
Set P478 to the source for the actual value.
Start signal (P68 or P69) starts the PID controller.
Check connection for actual value signal.
Caused by functionality (see chapter 8.3).
If undesired: Deactivate Energy saving function
(P1511) or select an operation mode, that doesn't
switch off the I/O's.
