Note:

1. NC represents “No connection”, which is for internal use only. Do not connect to NC, or it may damage

the servo drive.

2. When the source of the pulse input is open collector NPN or PNP type equipment, you must

connect the external power (24V ± 10%) to the PULL HI pins.

 Do not connect the 24V power to the SIGN+ and SIGN- pins at the same time, or the circuit

elements will be damaged.

 Do not connect the 24V power to the PULSE+ and PULSE- pins at the same time, or the

circuit elements will be damaged.
