Error Codes of Alarm 300500
Extension 2 NC drive number
Explanation 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
− Excessive voltage level of C/D track
− Check encoder alignment and EMC measures.
Remedy
− New startup
− Check MODE
− Replacing the motor
Error code 0045H
Error text BERO was selected with FEINSYNC.
Extension 1 -
Extension 2 NC drive number
Explanation 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.
Remedy 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.
Error code 0046H
Error text The NC attempted a drive power-up without loading the drive software. Ramp-up was
interrupted.
Extension 1 -
Extension 2 -
Explanation With drive software 4.02 and higher a drive power-up is only possible when the drive
software is being loaded.
Remedy Reload drive software.
Error code 0047H
Error text System tried to run two axes with HSA at performance 1 or STandard.
