3.1.4 Interface Circuits
Sequence Input Circuit Interface
The sequence input circuit interface connects through a relay or open-collector tran-
sistor circuit. Select a low-current relay otherwise a faulty contact will result.
Output Circuit Interfaces
Any of the following three types of servo amplifier output circuits can be used. Con-
nect an input circuit at the host controller following one of these types.

Connecting to an Open-Collector Output Circuit (Alarm Code Outputs)
Alarm code signals are output from open-collector transistor output circuits.
Connect an open-collector output circuit through a photocoupler, relay, or line
receiver circuit.
The maximum allowable voltage and current capacities for open-collector circuits are:
• V
