USING STO FUNCTION
For items other than the ones described in this chapter, refer to chapter 13 in "MR-J4-_B_(-RJ) Servo
Amplifier Instruction Manual".
Wiring example
In the parallel drive system, multiple drive units drive one servo motor. Wire the STO signal to all the drive units.
The following shows a system that drives a servo motor with four MR-J4-DU_B4-RJ100 drive units and four MR-CV_ power
regeneration converter units connected. For the number of drive units required to be connected to one servo motor, refer to
the following.
