Pullout Detection

Was bedeutet Sto ?

The drive has detected that the motor has pulled out of synchronization, often due to severe overload or insufficient torque. This results in the motor losing speed control.

1. 1

   Inspect mechanical load for binding, misalignment, or severe overload conditions that could cause motor pullout.

2. 2

   Verify drive parameters including motor nameplate data (voltage, current, frequency, RPM), acceleration/deceleration times, and current limit settings (e.g., C1-01) against motor specifications and application requirements.

3. 3

   Inspect motor power cabling for loose connections, damage, or signs of overheating at both the drive and motor terminals.

4. 4

   Measure motor phase currents while the drive attempts to run, checking for balance and excessive draw, which may indicate an overload or motor issue.
