3.5 Power line circuit

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.

CAUTION Use the trouble signal to switch power off. Otherwise, a regenerative brake transistor fault or the like may overheat the regenerative brake resistor, causing a fire.

3.5.1 Connection example

Wire the power supply/main circuit as shown below so that power is shut off and the servo-on signal 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.
