SINUMERIK 840D/840Di/810D Diagnostics Guide (DA) – 11.02 Edition
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.
- Channel not ready.
- If the axis is a single axis when this alarm is triggered, the alarm is only effective for this
axis (not effective for e.g. the channel or mode group)
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
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)
On absolute encoders, the resolution of the incremental and absolute track supplied by
the drive is also checked for consistency.
• Motor measuring system: MD1005, MD1022
• Direct measuring system: MD1007, MD1032
The two drive machine data must have a defined relation to one another. If the conditions
listed below are not fulfilled, an alarm is output.
2.1 Rotary measuring system ($MA_ENC_IS_LINEAR[] == FALSE)
MD1022/MD1005 == 4 * n [n=1,2,3...] (motor measuring system)
MD1032/MD1007 == 4 * n [n=1,2,3...] (direct measuring system)
2.2 Linear measuring system ($MA_ENC_IS_LINEAR[] == TRUE)
MD1005/MD1022 == 4 * n [n=1,2,3...] (motor measuring system)
MD1007/MD1032 == 4 * n [n=1,2,3...] (direct measuring system)
