- 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 parame-
ters of the quadrant error compensation (friction compensation), if necessary switch off
the compensation with MD 32500 FRICT_COMP_ENABLE.
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
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)
Reactions: - 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 evalu-
ated, if necessary. They could be the cause of incorrect entries in MD1022/MD1032
which are read out of the encoder by the drive.
Program Con- Switch control OFF - ON.
tinuation:
26003
Axis %1 parameterization error: lead screw pitch
Parameters: %1 = Axis name, spindle number
Definitions: The pitch of the ballscrew/trapezoidal leadscrew set in the axis-specific machine data
31030 LEADSCREW_PITCH is zero.
