Flowchart
Press the EMERGENCY STOP button
and switch on the machine.
Look up in MP100 at which position
the axis concerned is defined.
Then set this axis inactive in MP10.
Restart the control.
Deselecting an axis
Do not acknowledge the Power interrupted
message, but call the MP list immediately.
Disconnect the postion encoder,
the speed encoder and PWM interface
for the axis concerned.
Do error messages
still occur?
The errors are not limited to one axis.
There are further faulty axes/devices
or general errors.
The errors are limited to one
axis. Find the error cause!
Yes
No
Switch off the machine.
When using UM inverter modules:
The window Hardware/firmware change
detected appears, as the PWM interface
was disconnected between UM and CC.
Accept this change.
Note
It may be impossible to deselect individual axes when the machine kinematics is active, or the
PLC program may prohibit traversing the machine when axes are missing.
--> Ask the machine manufacturer!
Attention
It is not sufficient to deactivate a suspicious axis with machine parameter MP10 (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.
