Cause : Motor blocked comes when Motor has been operating at the torque limit longer than the time specified in p2177 and below the speed threshold set in p2175.

This signal can also be triggered if the speed is oscillating and the speed controller output repeatedly goes to its limit. It may also be the case that thermal monitoring of the power unit reduces the current limit (see p0290), thereby causing the motor to decelerate.

- check that the motor can freely move.
- check the effective torque limit (r1538, r1539).
- check the parameter, message "Motor blocked" and if required, correct (p2175, p2177).
- check the direction of rotation enable signals for a flying restart of the motor (p1110, p1111).
- for U/f control: check the current limits and acceleration times (p0640, p1120).
