IMMEDIATELY
Cause:
Motor has been operating at the torque limit longer than the time specified in p2177 and below the speed threshold
set in p2175.
Remedy:
- check that the motor can freely rotate.
- check the torque limit: For a positive direction of rotation r1538, for a negative direction of rotation r1539.
- check the parameter, message "Motor locked" and if required, correct (p2175, p2177).
- check the inversion of the actual value (p0410).
- check the motor encoder connection.

F07901
Drive: Motor overspeed
Reaction:
OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY
Cause:
The maximum permissible speed was either positively or negatively exceeded.
The maximum permissible positive speed is formed as follows: Minimum(p1082, CI: p1085) + p2162. The maximum
permissible negative speed is formed as follows: Maximum(-p1082, CI: 1088) - p2162.
Remedy:
For a positive direction of rotation:
- check r1084 and if required, correct p1082, CI: p1085 and p2162.
For a negative direction of rotation:
- check r1087 and if required, correct p1082, CI: p1088 and p2162.
F07902 (N, A)
