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 (3-phase: L1, L2, and L3, 1-phase: L1 and L3). 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 and L21) simultaneously with the main circuit

power supply or before switching on the main circuit power supply. If the control circuit power

supply is turned on with the main circuit power supply off, and then the servo-on command is

transmitted, [AL. E9 Main circuit off warning] will occur. Turning on the main circuit power supply

stops the warning and starts the normal operation.

3) The servo amplifier receives the servo-on command within 3 s to 4 s after the main circuit power

supply is switched on.

(Refer to paragraph (2) of this section.)
