3.4.3 Sequence Output Circuit
There are four types of SERVOPACK output circuits:
(1) Open-collector Output Circuit
CN1 connector terminals 37 to 39 (alarm code output) are explained below.
Alarm code signals (ALO1, ALO2, ALO3) are output from open-collector transistor output circuits. Connect
an open-collector output circuit through a photocoupler, relay or line receiver circuit.
Note: The maximum allowable voltage and current capacities for open-collector output circuits are as follows.
• Voltage: 30 VDC
• Current: 20 mA DC
(2) Photocoupler Output Circuit
Photocoupler output circuits are used for servo alarm (ALM), servo ready (/S-RDY), and other sequence out-
put signal circuits. Connect a photocoupler output circuit through a relay or line receiver circuit.
Note: The maximum allowable voltage and current capacities for photocoupler output circuits are as follows.
• Voltage: 30 VDC
• Current: 5 to 50 mA DC
