5.2.5 Sequence Output Circuit
The signal output circuit from the SERVOPACK is described below.
(1) Photocoupler Output Circuit
The brake signal (/BK) output signal uses a photocoupler output circuit. Connect a photocoupler output circuit
through a relay circuit or line-receiver circuit.
Note: The maximum allowable voltage and the allowable range of current capacity for photocoupler output circuits are as
follows.
•
Voltage: 30 VDC
•
Current: 5 to 50 mA DC
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 brake will not
work. This could damage the machine or cause an accident resulting in death or injury.
