3.4 Examples of Connection to Host Controller
This section shows examples of SERVOPACK I/O signal connection to the host controller.
3.4.1 Sequence Input Circuit
(1) Photocoupler Input Circuit
CN1 connector terminals 6 to 13 are explained below.
The sequence input circuit interface is connected through a relay or open-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.
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 1. The connection examples in 3.2.3 Example of I/O Signal Connections are sink circuit connections.
2. The ON/OFF polarity differs between when a sink circuit is connected and when a source circuit is connected.
