oH5
Motor Overheat (NTC Input)
Yaskawa · J1000 AC Drive
What does oH5 mean?
The motor temperature, as directly monitored via an NTC thermistor input, has exceeded the alarm level set in parameter L1-16 (or L1-18 for motor 2). This indicates the motor itself is running excessively hot, likely due to prolonged overload or high ambient temperatures. Sustained overheating can lead to irreversible damage to motor windings and premature motor failure.
