Axis %1 clamping monitoring
%1 = Axis name, spindle number
The clamped axis is to be pushed out of its setpoint position. The permissible difference is
defined in the axis-specific machine data 36050 CLAMP_POS_TOL.
Clamping of an axis is activated with the axis-specific interface signal DB 31 - 48, DBX
2.3: "Clamping process active".
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- 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.
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).
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 parameterization error: friction compensation
%1 = Axis name, spindle number
The parameterization of the adaptation characteristic in the quadrant error compensation
is not allowed because acceleration value 2 (MD 32560 FRICT_COMP_ACCEL2 is not
between acceleration value 1 (MD 32550 FRICT_COMP_ACCEL1) and acceleration
value 3 (MD 32570 FRICT_COMP_ACCEL3).
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- 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.
Please inform the authorized personnel/service department. Check the setting parame-
ters of the quadrant error compensation (friction compensation), if necessary switch off
the compensation with MD 32500 FRICT_COMP_ENABLE.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 encoder %2 parameterization error: number of encoder marks
%1 = Axis name, spindle number
%2 = Encoder number
1. Rotary measuring system ($MA_ENC_IS_LINEAR[]==FALSE)
The number of encoder marks set in MD31020 $MA_ENC_RESOL[] does not correspond
to the value in the drive machine data MD1005 or zero has been entered in one of the two
machine data.
2. Absolute measuring system with EnDat interface ($MA_ENC_TYPE[]==4)
