Input 3: Z LIM
The input must be activated in the settings! Input for limit switch of the Z axis. You can use
potential-free contacts of a mechanical limit switch or inductive proximity switches (see below)
When the input is activated, the control switches to a safe state and ends running cycles until a
release has been given with the STOP key.
Input 3: X LIM
Like Z LIM, only for X axis
Input 4: ERROR
The input must be activated in the settings! input for an error signal, e.g. from the motor driv-
ers. All cycles are immediately interrupted in the event of a trip until the fault condition has
been rectified and a release with the STOP key has been given.
Wiring examples
In addition to the input connection, 12V is available, as are two GND terminals (GND) to ensure
the power supply of sensors.
