3.3.2 Power-on sequence
(1) Power-on procedure
1) Always wire the power supply as shown in above section 3.1 using the magnetic contactor with the main
circuit power supply (three-phase: L
1
, L
2
, L
3
, single-phase: L
1
, L
2
). 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 L

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) of this section.)

(3) Forced stop
CAUTION
Install an forced stop circuit externally to ensure that operation can be stopped and
power shut off immediately.
If the controller does not have an forced stop function, make up a circuit that switches off main circuit power
as soon as EM1 is turned off at a forced stop. When EM1 is turned off, the dynamic brake is operated to
stop the servo motor. At this time, the display shows the servo forced stop warning (E6).
During ordinary operation, do not use forced stop (EM1) to alternate stop and run. The service life of the
servo amplifier may be shortened.

Twisted wire: Use the cable after stripping the sheath and twisting the core. At this time, take care to
avoid a short caused by the loose wires of the core and the adjacent pole. Do not solder
the core as it may cause a contact fault. Alternatively, a bar terminal may be used to put
the wires together.
