How can resolve problem oH3 Motor over-heating warning in delta ME300 series Drive ?
Cause : Motor over-heating warning.
The AC motor drive detects the temperature inside the motor is too high.
Pr.03-00 = 6 (PTC), PTC input level > Pr.06-30 (default = 50%).
Check the cooling system to make it work normally.
Decrease low-speed operation time.
Change to the dedicated motor for the drive.
Increase the motor capacity.
Increase the setting values for Pr.01-12–01-19 (accel./ decel. time).
Warning treatment 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.
