Motor overheating
(oH3) PTC
Motor overheating (PTC) (Pr.03-00–Pr.03-02=6 PTC),
when PTC input > Pr.06-30, the fault treatment acts
according to Pr.06-29.
Action and Reset
Action level
PTC input value > Pr.06-30 setting (Default = 50%)
Action time
Immediately act
Fault treatment parameter
Pr.06-29
0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: No warning
Reset method
When Pr.06-29=0, oH3 is a “Warning”. The “Warning” is automatically cleared.
When Pr.06-29=1 or 2, oH3 is a “Fault”. You must reset manually.
Reset condition
Immediately reset
Record
When Pr.06-29=1 or 2, oH3 is a “Fault”, and the fault is recorded.
Cause
Corrective Actions
Motor shaft lock
Remove the shaft lock.
The load is too large
Reduce the load.
Increase the motor capacity.
Ambient temperature is too high Change the installed place if there are heating devices in the surroundings.
Install/ add cooling fan or air conditioner to lower the ambient temperature.
Motor cooling system error
Check the cooling system to make it work normally.
Motor fan error
Replace the fan.
Operate at low-speed too long.
Decrease low-speed operation time.
Replace the motor with a dedicated to VFD model.
Increase the motor capacity.
Accel./Decel. time and working
cycle are too short
Increase the setting values for Pr.01-12–01-19 (accel./decel. time)
V/F voltage is too high
Adjust settings for Pr.01-01–01-08 (V/F curve), especially the setting value for
the mid-point voltage (if the mid-point voltage is set too low, the load capacity
decreases at low speed).
Check if the motor rated current
matches that on the motor
nameplate.
Reset to the correct motor rated current.
Check if the PTC is properly set
and wired.
Check the connection between PTC thermistor and the heat protection.
Check if the setting for stall
prevention is correct.
Set the stall prevention to the proper value.
Unbalanced three-phase
impedance of the motor
Replace the motor.
Harmonics are too high.
Use remedies to reduce harmonics.
