Power-On Sequence - Mitsubishi Electric EZMOTION MR-E Super MR-E-10A-QW003 Instruction Manual

3. SIGNALS AND WIRING

3.7.3 Power-on sequence

(1) Power-on procedure
1) Always wire the power supply as shown in above section 3.7.1 using the magnetic contactor with the
power supply (three-phase 200V: L
sequence to switch off the magnetic contactor as soon as an alarm occurs.
2) The servo amplifier can accept the servo-on (SON) 2s or more after the power supply is switched on.
Therefore, when SON is switched on simultaneously with the power supply, the base circuit will switch
on in about 1 to 2s, and the ready (RD) will switch on in further about 20ms, making the servo amplifier
ready to operate. (Refer to paragraph (2) in this section.)

3) When the reset (RES) is switched on, the base circuit is shut off and the servo motor shaft coasts.

CAUTION
Make up a circuit which shuts off power as soon as EMG-VIN are opened at an emergency stop. To ensure
safety, always install an external emergency stop switch across EMG-VIN. By disconnecting EMG-VIN, the
dynamic brake is operated to bring the servo motor to a sudden stop. At this time, the display shows the
servo emergency stop warning (AL.E6).
During ordinary operation, do not use the external emergency stop signal to alternate stop and run.
The servo amplifier life may be shortened.
Also, if the start signal is on or a pulse train is input during an emergency stop, the servo motor will rotate
as soon as the warning is reset. During an emergency stop, always shut off the run command.
