Sscnet Iii Cable Connection - Mitsubishi Electric MR-J4W2-0303B6 Instruction Manual

3. SIGNALS AND WIRING
(2) Digital output interface DO-1
This is a circuit in which the emitter of the output transistor is the output terminal. When the output
transistor is turned on, the current will flow from the output terminal to a load.
A maximum of 2.6 V voltage drop occurs in the servo amplifier.

3.9 SSCNET III cable connection

(1) SSCNET III cable connection
For the CN1A connector, connect the SSCNET III cable connected to a controller in host side or a servo
amplifier of the previous axis. For CN1B connector, connect SSCNET III cable connected to servo
amplifier of the next axis. For CN1B connector of the final axis, put a cap came with servo amplifier.

Note. If the voltage drop (maximum of 2.6 V) interferes with the relay operation, apply high
voltage (maximum of 26.4 V) from external source.
POINT
Do not look directly at the light generated from CN1A/CN1B connector of the
servo amplifier or the end of SSCNET III cable. The light can be a discomfort
when it enters the eye.
