25202

Axis %1 waiting for drive

Parameters: %1 = Axis name, spindle number
Definitions: Drive group error (self-clearing).
Reaction: Interface signals are set.
Alarm display.
Remedy: For PROFIdrive only:
Wait for the drive. This alarm reveals similar problems to alarm 25201 (see that alarm). It is continuously active during
power-up if the drive does not communicate (e.g. if the PROFIBUS connector has fallen out). Otherwise, the alarm is
active only briefly and is replaced by alarm 25201 after an internal timeout in the event of a permanent problem.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.

Axis %1 clamping monitoring

Parameters: %1 = Axis name, spindle number
Definitions: The clamped axis has been pushed out of its setpoint position. The permissible difference is defined in the axis-specific
MD36050 $MA_CLAMP_POS_TOL.
Clamping an axis is activated with the axis-specific interface signal DB380x DBX0002.3 (Clamping process active).
The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Determine the position deviation to the setpoint position and, depending on the results, either increase the permissible
tolerance in the MD or mechanically improve the clamping (e.g. increase clamping pressure).
Program Teileprogramm neu starten.Clear alarm with the RESET key in all channels of this mode group. Restart part program.

Axis %1 parameterization error: friction compensation

Parameters: %1 = Axis name, spindle number
Definitions: The parameterization of the adaptation characteristic in the quadrant error compensation is not allowed because
acceleration value 2 (MD32560 $MA_FRICT_COMP_ACCEL2 is not between acceleration value 1 (MD32550
$MA_FRICT_COMP_ACCEL1) and acceleration value 3 (MD32570 $MA_FRICT_COMP_ACCEL3).
The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Please inform the authorized personnel/service department.
Check the setting parameters of the quadrant error compensation (friction compensation), if necessary switch off the
compensation with MD32500 $MA_FRICT_COMP_ENABLE.
Program Teileprogramm neu starten.Clear alarm with the RESET key in all channels of this mode group. Restart part program.
