Deselecting an axis
Switch off the machine.
Disconnect the position encoder,
the speed encoder and the PWM interface
of the axis concerned.
Press the EMERGENCY STOP button
and switch on the machine.
Do not acknowledge the Power interrupted
message but call the MP list.
In MP 100, you can see at which location the axis
concerned is defined.
In MP 10, set this axis inactive.
Restart the control.
Do error messages
continue to occur?
The errors are not limited to one axis.
There are other faulty axes / devices,
or general faults.
Note
It is possible that individual axes cannot be deselected when the machine kinematics is
active or that the PLC program prohibits that the machine can be moved when axes are
missing. --> Ask the machine manufacturer!
Caution
It is not sufficient to deactivate a suspicious axis with machine parameter 10 (without
disconnecting suspicious units).
The units concerned (e.g., position encoder for this axis) are not monitored any more but still
supplied with power. The defective scale can thus influence the low voltages of the control,
for example.
No
Yes
The errors are limited
to one axis. Find out
the error cause.
