26001
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 (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).
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
MD 32500 FRICT_COMP_ENABLE.
Program
Continuation:
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
26002
Axis %1 encoder %2 parameterization error: number of encoder marks
Parameters:
%1 = Axis name, spindle number
%2 = Encoder number
Definitions:
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)
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. Adjust machine data. For absolute
encoders, pending drive alarms indicating encoder problems should be evaluated, if necessary. They
could be the cause of incorrect entries in MD1022/MD1032 which are read out of the encoder by the
drive.
Program
Continuation:
Switch control OFF - ON.
