Technical Specifications of the Digital Inputs

The IP 267 can calibrate and limit the traversing range via five digital inputs
(24 V). Limit switches for initiating deceleration can be connected to the inputs I -
and I +. You can set the method of signal evaluation ("0"-active or "1"-active)
when configuring the module. The STOP input terminates the traversing
movement and also initiates deceleration; it always has the same signal
evaluation as inputs I - and I+. Reference switches (BEROs, etc.) can be connected
to the REF input. The PD input is for connecting emergency limit switches and the
input is always "0"-active (NC). Pulse output is inhibited immediately when the
emergency limit switch (PD) responds. The red "ABT" LED on the frontplate of
the IP 267 lights up. You must proceed as follows if the IP is to accept new
positioning jobs:
• The emergency limit switch must be enabled again.
• The configuration data on the IP 267 must be deleted, causing the "ABT" and
"RDY" LEDs to go out.
• The configuration data must be transferred back to the IP 267. The green
"RDY" LED lights up when the module is configured.
Note:
The IP 267 is disabled when the emergency limit switch responds and it can
only accept new positioning jobs if you delete the old configuration data and
then reconfigure the module.
