NC drive number
Rotor position synchronization contains an error (drive software 2.5 only).
The difference between the first part of rotor position synchronization (coarse synchroni-
zation) and the second part (fine synchronization to the active encoder zero marker) is
greater than 45 electrical.
An excessive difference can occur due to:
- Incorrect encoder alignment
- EMC problems on the zero marker signal
- Voltage level of C/D track too high
- Check encoder alignment and EMC measures
- New startup
- Check MODE
- Replace motor

NC drive number
The NC has entered either an encoder with distance-coded reference point markers or a
BERO proximity switch in register $1D of the motor measuring system of the PCU ASIC.
This is not allowed during fine synchronization which is activated by power-up, by zero
monitoring errors or by deselection of the parking axis.
The NC/PLC is not allowed to enter an encoder with distance-coded reference point
markers or a BERO proximity switch in register $1D of the motor measuring system of the
PCU ASIC following power-up, zero monitoring errors or deselection of the parking axis.

With drive software 4.02 and higher a drive power-up is only possible when the drive soft-
ware is being loaded.
Reload drive software.
