Connection PTO (CN4, Pulse Train Out)

General

5 V signals are available at the PTO (Pulse Train Out, CN4) output. Depending on parameter PTO_mode, these signals are ESIM signals (encoder simulation) or logically fed through PTI input signals (P/D signals, A/B signals, CW/CCW signals). The PTO output signals can be used as PTI input signals for another drive. The signal level corresponds to RS422, see Output PTO (CN4). The PTO output supplies 5 V signals, even if the PTI input signal is a 24 V signal.

Availability

Available with firmware version ≥V01.04.

PTO: Logically Fed Through PTI Signals

At the PTO output, the PTI input signals can be made available again to control a subsequent drive (daisy chain). Depending on the input signal, the output signal can be of type P/D signal, A/B signal or CW/CCW signal. The PTO output supplies 5 V signals.

Connecting PTO

Connect the connector to CN4. Verify correct pin assignment.
Verify that the connector locks snap in properly.
