3.5.3 Power-on sequence

(1)Power-on procedure

1)Always wire the power supply as shown in above Section 3.5.1 using the magnetic contactor with the main circuit power supply (3-phase 200V: L1, L2, L3, 1-phase 230V: L1, L2). Configure up an external sequence to switch off the magnetic contactor as soon as an alarm occurs.

2)Switch on the control circuit power supply L11, L21 simultaneously with the main circuit power supply or before switching on the main circuit power supply. If the main circuit power supply is not on, the display shows the corresponding warning. However, by switching on the main circuit power supply, the warning disappears and the servo amplifier will operate properly.

3)The servo amplifier can accept the servo-on command within 3s the main circuit power supply is switched on. (Refer to paragraph (2) in this section.)

Servo-on command		ON
(from controller)		OFF

(3) Forced stop

CAUTION	Install an emergency stop circuit externally to ensure that operation can be
	stopped and power shut off immediately.

If the controller does not have an emergency stop function, make up a circuit which shuts off main circuit power as soon as EM1-SG are opened at a forced stop. To ensure safety, always install a forced stop switch across EM1-SG. By disconnecting EM1-SG, the dynamic brake is operated to bring the servo motor to a stop. At this time, the display shows the servo forced stop warning (E6).

During ordinary operation, do not use forced stop signal to alternate stop and run. The service life of the servo amplifier may be shortened.
