26018 Axis %1 setpoint output drive %2 used more than once
Parameters: %1 = Axis name, spindle number
%2 = Drive number
Definitions: The same setpoint assignment has been allocated more than once.
MD30110 $MA_CTRLOUT_MODULE_NR contains the same value for different axes.
PROFIdrive: The stated MDs contain the same values for different axes, or different entries in
$MN_DRIVE_LOGIC_ADDRESS contain the same values.
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.
Remedy: Please inform the authorized personnel/service department. Avoid dual assignment of the setpoint by
correcting MD30110 $MA_CTRLOUT_MODULE_NR. Also check the selected bus type MD30100
$MA_CTRLOUT_SEGMENT_NR.
Program Con- Switch control OFF - ON.
tinuation:
26019 Axis %1 encoder %2 measurement not possible with this controller
module
Parameters: %1 = NC axis number
%2 = Encoder number
Definitions: If the MD MD13100 $MN_DRIVE_DIAGNOSIS[8] contains a value not equal to zero, then the control
has found at least one control module which does not support measuring. Measuring was pro-
grammed from the part program for the associated axis.
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: If possible, modify the measuring motion such that the axis concerned does not have to travel; do not
program this axis in the MEAS block again. However, it is then no longer possible to query a measured
value for this axis. Otherwise, exchange the controller module for one that supports measuring. See
MD13100 $MN_DRIVE_DIAGNOSIS[8].
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26022 Axis %1 encoder %2 measurement with simulated encoder not possible
Parameters: %1 = NC axis number
%2 = Encoder number
Definitions: Alarm occurs on the control when a measurement was made without the encoder hardware (simulated
encoder).
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: - Please inform the authorized personnel/service department.
- If possible, modify the measuring motion such that the axis concerned does not have to travel; do
not program this axis in the MEAS block again. However, it is then no longer possible to query a mea-
sured value for this axis.
- Ensure that measurement is not taking place with simulated encoders (MD30240 $MA_ENC_TYPE).
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26024 Axis %1 machine data %2 value changed
Parameters: %1 = Axis name, spindle number
%2 = String: MD identifier
