8.6 Operating Using Position Control8.6.3 Position ReferenceThe servomotor positioning is controlled by inputting a pulse train reference.The pulse train output form from the host controller corresponds to the following:• Line-driver Output• +24V Open-collector output• +12V Open-collector output• +5V Open-collector outputIMPORTANT•Precautions for Open-collector OutputWhen the open-collector output is used, input signal noise margin lowers.

The interval from the time the servo ON signal is turned ON until a reference pulse is input mustbe at least 40 ms, otherwise the reference pulse may not be received by the SERVOPACK.2. The error counter clear signal must be ON for at least 20 µs.88-53
