3. SIGNALS AND WIRING

3.13.1 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 emergency stop is made valid, a controller emergency stop,
or a servo motor thermal relay alarm is made valid. A no-fuse breaker (NFB) must be used with the input
cables of the power supply.
NFB
3-phase
200 to 230VAC
Emergency stop
servo-on
Note 1. When using the external dynamic break, refer to section 13.1.4.
2. Cooling fan power supply of the HA-LFS11K2 servo motor is 1-phase. Power supply specification of the cooling fan is
different from that of the servo amplifier. Therefore, separate power supply is required.
