3.5 Power line circuit
CAUTION
When the servo amplifier has become faulty, switch power off on the amplifier
power side. Continuous flow of a large current may cause a fire.
Switch power off at detection of an alarm. Otherwise, a regenerative brake
transistor fault or the like may overheat the regenerative brake resistor, causing a
fire.
POINT
For the power line circuit of the MR-J2S-11KB to MR-J2S-22KB, refer to
Section 3.12 where the power line circuit is shown together with the servo
motor connection diagram.

motor connection diagram.
3.5.1 Connection example
Wire the power supply/main circuit as shown below so that power is shut off and the servo-on command
turned off as soon as an alarm occurs, a servo forced stop is made valid, or a controller emergency stop is
made valid. A no-fuse breaker (NFB) must be used with the input cables of the power supply.
