Capacitor module overheating fault
corrective action
Contact the dealer or manufacturer to return the motor drive to the
factory for repair.
20
Cooling fan does not run properly.
corrective action
Check if the cooling fan is covered by dust and needs to be cleaned.
Contact the dealer or manufacturer to return the motor drive to the
factory for repair if necessary.
21
The output current causes the motor drive to be overload. If the
output current is 150% higher than the drive’s rated current, the
motor drive can sustain the output for a maximum of 60 seconds.
corrective action
1. Check if the motor is overloaded.
2. Increase the output capacity of the motor drive.
22
The output current causes the motor to be overload. If the output
current is 150% higher than the drive’s rated current, the motor can
sustain the output for a maximum of 60 seconds.
corrective action
1. Check the setting for motor full-load current (Pr.05-01).
2. Check if motor is overloaded and change to a higher power
motor.
24
Motor overheating
The AC motor drive internal temperature exceeds the setting in
Pr.06-27 (PTC level).
corrective action
1. Make sure that the motor is not obstructed.
2. Ensure that the ambient temperature falls in the specified
temperature range.
3. Change to a higher power motor.
26
The ot1 and ot2 fault codes appear when the following conditions
occur:
- The output current exceeds the setting in Pr.06-06 (Over-torque
Detection Level (OT1)> and Pr.06-09 (Over-torque Protection
Level (OT2).
