Function Modules
Using a limit switch on the digital inputs, IP 267 can monitor the limits of a traversing range and stop
the traversing movement when the permissible range limit is exceeded.
The activated input "external stop" causes a calculated decelerating of the traversing movement.
An emergency limit switch can be installed at input "IS" (pulse inhibit). When this switch responds,
the pulse output is interrupted immediately.
For a reference point approach operation, an additional switch can be connected at input REF that
lies within the traversing zone. The reference point approach operation is also possible without this
switch.
Status LEDs provide you with the following information.

NEUTRAL
Installation
• Plug the IP 267 into a bus unit like any other I/O module.
• With the S5-90U, a maximum of 2 IP 267 modules (limited by current consumption) can be
plugged in at slots 0 to 5.
• With the S5-95U, a maximum of 6 IP 267 modules (limited by current consumption) can be
plugged in at slots 0 to 7.
• Connect the external switches to the DIs of the IP 267 via the terminal block.
• Connect the stepper motor's power section to the 9-pin subminiature D female connector.
Addressing
The IP 267 is addressed like an analog module.
