CAUTION

3.7.1 Connection example

Wire the power supply and main circuit as shown below so that the servo-on (SON) turns off as soon as
alarm occurrence is detected and power is shut off.
A no-fuse breaker (NFB) must be used with the input cables of the power supply.
(1) For 3-phase 200 to 230VAC power supply
3-phase
200 to 230 VAC
When the servo amplifier has become faulty, switch power off on the servo
amplifier power side. Continuous flow of a large current may cause a fire.
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.
