Reaction: Alarm Display; Parameters: %1 = Axis Name, Spindle Number - Siemens Sinumerik 840D sl Diagnostic Manual

03/2009
Remedy: Please inform the authorized personnel/service department. Rereferencing/resynchronization of the
absolute encoder; attach absolute encoder on the load side and configure correctly (e.g. MD 31040
$MA_ENC_IS_DIRECT).
If an absolute encoder with a serial number is replaced, the drive BOT file for this drive must be saved
(because of the new serial number).
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
26031 Axis %1 configuration error master-slave
Parameters: %1 = Axis name, spindle number
Definitions: The alarm is output when the same machine axis has been configured as a master and a slave axis.
Each of the axes in the master/slave link can be operated either as master or slave.
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: - Check machine data for all linked axes and correct if necessary:
- MD 37250 $MA_MS_ASSIGN_MASTER_SPEED_CMD
- MD 37252 $MA_MS_ASSIGN_MASTER_TORQUE_CTR.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26032 [Channel %1: ] Axis %2 master-slave not configured
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The master-slave coupling could not be activated because of incomplete configuration.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check the current configuration of the master-slave coupling.
The configuration can be modified via the MASLDEF instruction or the machine data MD37250
$MA_MS_ASSIGN_MASTER_SPEED_CMD and MD37252
$MA_MS_ASSIGN_MASTER_TORQUE_CTR.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26050 Axis %1 parameter set change from %2 to %3 not possible
Parameters: %1 = Axis name, spindle number
%2 = Index: current parameter block
%3 = Index: new parameter block
Definitions: The parameter block change cannot be performed without jumps. This is due to the content of the
parameter block to be switched on, e.g. different load gear factors.
Reaction: The NC switches to follow-up mode.
Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: In the following cases, the parameter block change is carried out via MD31060
$MA_DRIVE_AX_RATIO_NUMERA and MD31050 $MA_DRIVE_AX_RATIO_DENOM without an
alarm, even with different load gear ratio settings:
1. If no position control is active (e.g. in follow-up mode or if spindle is in speed-controlled mode).
2. For position control with the direct encoder.
3. For position control with the indirect encoder (the calculated load position difference must not
exceed the value indicated in MD36500 $MA_ENC_CHANGE_TOL).
Program Con- Clear alarm with the RESET key. Restart part program
