motor becomes torqueless (coasts).
•
The error type can be congured in 0x2C60.
•
Check seng of the motor data.
•
Ensure that the motor is at a standsll during
the pole posion idencaon process.
•
Ensure that the motor and inverter match
each other in terms of power.

•
The error can only be reset aer a blocking
me of 1 s.
•
The error type can be congured in
0x2D46:002 (P353.02).
•
Check motor load.
•
Check drive dimensioning.
•
Check warning/error threshold set in
