2.6 Connection Example to Host Controller
For products not described in this manual, be sure to refer to the manual attached to the corresponding
product. Refer to the connection diagram described here.

The servomotor specified in the connection diagram is equipped with a brake. If the servomotor is
equipped with no brake, the Br terminal is not provided.

Connection of connector 4 (CN4) is unnecessary for the operation of the servomotor. Use it to
measure or monitor the speed waveform and torque waveform of the servomotor with a measuring
instrument or similar.

Connect a battery at connector 5 (CN5) to configure an absolute system.
It is unnecessary if the absolute system is not configured.

To drive a servomotor, the main power must be supplied.

Prepare separate power supplies for 24 VDC sequence I/O (CN1) and 24 VDC brake.
This is to isolate the effects of voltage fluctuation caused by counter electromotive force generated
by power-on and -off of the brake coil. There is no polarity in the brake power supply input.
