2.6 Power-on sequence
POINT
The voltage of analog monitor output, output signal, etc. may be unstable at
power-on.
2.6.1 MR-J4-_A_-RJ 100 W or more
(1) Power-on procedure
1) Always use a magnetic contactor for the main circuit power supply wiring (L1/L2/L3) as shown in
section 3.1 of "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual". Configure 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 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 receives the SON (Servo-on) 4 s to 5 s after the main circuit power supply is
switched on. Therefore, when SON (Servo-on) is switched on simultaneously with the main circuit
power supply, the base circuit will switch on in about 4 s to 5 s, and the RD (Ready) will switch on
in further about 5 ms, making the servo amplifier ready to operate. (Refer to (2) of this section.)
4) When RES (Reset) is switched on, the base circuit is shut off and the servo motor shaft coasts.
