Connection PTI (CN5, Pulse Train In)

General

P/D (pulse/direction), A/B signals or CW/CCW signals can be connected to the PTI connection (Pulse Train In, CN5).

It is possible to connect 5 V signals or 24 V signals, see Input PTI (CN5). Pin assignments and cables are different.

Incorrect or interfered signals as reference values can cause unintended movements.

WARNING
	UNINTENDED MOVEMENT Use shielded twisted-pair cables. Do not use signals without push-pull in environments subject to interference. Use signals with push-pull in the case of cable lengths of more than 3 m (9.84 ft) and limit the frequency to 50 kHz. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Availability

Available with firmware version ≥V01.04.

WARNING
	UNINTENDED EQUIPMENT OPERATION Do not connect any wiring to reserved, unused connections, or to connections designated as No Connection (N.C.). Failure to follow these instructions can result in death, serious injury, or equipment damage.

Connecting Pulse Train IN (PTI) 5 V

Connect the connector to CN5. Verify correct pin assignment.
Verify that the connector locks snap in properly.

Connection Assignment PTI 24 V

Note that the wire pairs for 24 V signals require assignments different from those for 5 V signals. Use a cable that complies with the cable specification. Assemble the cable as shown in the illustration below.
