1 Alarms
1.5.1 Alarm description
Remedy
Check the encoder hardware (encoder, cable, connectors, absolute submodule). The SIPOS encoder must remain
stationary during transmission of the absolute value, the axis must therefore be held by the brake if necessary.
Note
Drive MD 1033 contains fine coding of errors.
1044* Battery absolute module
Scan
Cyclic, every 10 minutes
Effect
None
Explanation
The SIPOS encoder has a battery back-up on the absolute submodule so that the absolute position is not lost
even when switched off. The remaining capacity of this battery is checked by the absolute module approximately
every 10 minutes and an alarm is released if a critical minimum limit is reached.
Remedy
Replace the battery on the absolute module
(see SIPOS absolute encoder description)

Explanation
The designated axis is coupled to its master axis through a speed setpoint coupling. Setpoings should therefore
not be specified.
Remedy
Setpoints should not be specified for the slave axis.
