7.2.2.4 Inhibited & Delayed Trigger Mode
The Inhibited & Delayed Trigger Mode first debounces the trigger input signal with the inhibit
time. The inhibited trigger signal is then delayed with the rise/fall delay time and then copied
to the trigger out signal.

7.2.3 X4.8 and X4.9 Limit Switches
If on IO pin X4.8 and/or on X4.9 a limit switch is defined, the error behavior in case of an
active limit switch can be configured. The error is only generated on a powered motor which
is homed, so it is possible to exit the error state with a new homing request. For that reason
also the homed bit in the status word is cleared if moving into a limit switch.
Parameter Name UPID Description
Error Behavior 121Bh Error behavior of the configured limit switches:
• 0: No Error (maybe only used for homing)
• 1: Power Off
• 2: Quick Stop
7.2.4 X4.10 and X4.11 PTC 1 and PTC 2
On IO pins X4.10 and X4.11 PTC sensors can be connected to supervise an over
temperature of a motor and/or the transformer supply. The other side of the PTC has to be
connected to 24V. If the resistance is below 2kOhm the input is high. If it rises above
15kOhm the output is regarded as low. Typically, the transition low to high is between
5kOhm and 7kOhm. If the input rises, the corresponding bit in the warn word will be set after
the PTC Warn Time. After the PTC error time the corresponding error is set. The error only
can be acknowledged if the corresponding PTC warn bit has vanished.
