Motor over-heating (oH3)

Motor overheating warning.
The AC motor drive detects the temperature inside the motor is too high

When Pr.06-29=0, oH3 displays as “Warning”. When the temperature is
Pr.06-30 level, the oH3 warning automatically clears

Warning setting parameter

Error treatment: Pr.06-29
0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: No warning
When Pr.06-29=0 and when the temperature is Pr.06-30 level, the oH3
warning automatically clears.
When Pr.06-29=0 (“Warning”), it automatically resets.
