3.4.2 Connection Examples of Sequence Input Circuits to SERVOPACK

CN1 connector terminals 6 to 13 are explained below.
The sequence input circuit interface connects through a relay or open-collector transistor circuit. Select a low-
current relay otherwise a faulty contact will result.
24 VDC
Note: The 24 VDC external power supply capacity must be 50 mA minimum.
Use the sink circuit for the input circuit to the SERVOPACK.
