The motor brake cannot be driven directly. To drive the motor brake, be sure to use a relay.
When driving a load containing inductance component such as a relay, connect a
protection circuit (diode). Install a diode in the direction shown in the figure below.
The output circuit conguration is an open collector Darlington transistor output. Connects
to relays and optical isolators. When the transistor is on, connector-emitter voltage VCE
(SAT) is approximately 1V; a standard TTL IC does not satisfy VIL, and cannot be directly
connected.
The maximum rating of output circuit is 30V 50mA.
Pin No.13 – 18
The emitter of output transistor is common to COM- of control power.
Pin No.19, No.21
The emitter of output resistor is Pins No.20 and No.22 and independent of COM-.
