Page 14: Sequence Input Circuit
2.3.2 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. -
Page 15: Sequence Input Circuit
2.3.3 Sequence Input Circuit Incorrect wiring or incorrect voltage application to the output circuit may cause short-cir- cuit. If a short-circuit occurs as a result of any of these causes, the holding lock will not work. This could damage the machine or cause an accident resulting in death or injury. (1) Photocoupler Output Circuit Photocoupler output circuits are used for servo alarm (ALM), servo ready (/S-RDY), and other sequence out- put signal circuits. - Page 16 (2) Line Driver Output Circuit CN1 connector terminals, 17-18 (phase-A signal), 19-20 (phase-B signal), and 21-22 (phase-Z signal) are explained below.
