3.4.2 Sequence Input Circuit
(1) Photocoupler Input Circuit
CN1 connector terminals 40 to 47 are explained below.
The sequence input circuit interface is connected through a relay or op
en-collector transistor circuit. When
connecting through a relay, use a low-current relay. If a low-current relay is not used, a faulty contact may
result.
Note: The 24 VDC external power supply capacity must be 50 mA minimum.
For SEN input signal circuit, refer to 5.9.1 Absolute Data Request Signal (SEN). 
The SERVOPACK’s input circuit uses bidirectional photocoupler. Select either the sink circuit or the source
circuit according to the specifications required for each machine.
Note:  The connection examples in 3.2.3 to 3.2.5 show sink circuits.
• The ON/OFF polarity differs between when a sink circuit is connected and when a source circuit is connected.
