Note
● 1KM: Electromagnetic contactor; 1RY: Relay; 1D: Flywheel diode;
● DOs are set as fault output (ALM+/-); when the servo drive alarms, the power supply is cut
off automatically. This series does not have a built-in bleeder resistor, therefore connect an
external bleeder resistor between P and C if required.
