Motor temperature trip

What does 10019 mean?

The drive has detected an over-temperature condition in the motor. This can be due to a hardwired thermistor input (X10) detecting overheating from a PTC sensor, or from a serial encoder (e.g., Hiperface DSP) reporting excessive motor thermistor resistance. Failure to address this can lead to motor damage and shutdown.

• Motor winding over-temperature detected by PTC thermistor connected to X10 input (e.g., pin X10/1 and X10/2 resistance exceeding trip threshold, typically >1.65 kΩ).
• Motor feedback device (e.g., Hiperface, EnDat encoder) reporting an internal over-temperature condition from its integrated sensor.
• Excessive motor load or prolonged operation above rated torque, causing stator windings to overheat.
• Inadequate motor cooling due to blocked ventilation fins or failed external cooling fan (if equipped).
• Motor insulation degradation leading to increased losses and heat generation.

Click steps to track your progress.

1. 1

   Measure the resistance across motor thermistor terminals X10/1 and X10/2 on the drive; verify it is below the trip threshold (e.g., <1.65 kΩ).

2. 2

   Use diagnostic software to read the motor temperature value reported by the serial encoder and compare it to the motor's rated operating temperature.

3. 3

   Confirm the motor's operating load current (Parameter P1-03) does not continuously exceed the motor's rated current (Parameter P0-01).

4. 4

   Inspect motor cooling fins for obstruction by dust or debris and verify external cooling fan (if present) is operational and providing adequate airflow.

5. 5

   Check Parameter P1-32 (Motor thermal model) and P1-33 (Motor thermal time constant) for correct configuration matching the installed motor.

6. 6

   Allow the motor to cool down to ambient temperature before attempting to reset the fault and restart operation.
