Power-on procedure [A]
The voltage of analog monitor output, the output signal, or others may be unstable at power-on.
Power-on procedure
1.
Wire the power supply using a magnetic contactor between the power supply and the main circuit power supply (L1/L2/
L3) of a servo amplifier by referring to the following section. Switch off the magnetic contactor as soon as an alarm
occurs.
Page 22 Connection example of power circuit
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, the warning will disappear and the servo amplifier will operate properly if the main
circuit is powered on.
3.
The servo amplifier receives the SON (Servo-on) 2.5 s to 3.5 s after the main circuit power supply is powered on.
4.
Once RES (Reset) is turned on, the base circuit is shut off and the servo motor shaft coasts.
Timing chart
*1 For a linear servo system, this is "4.5 s to 5.5 s".
*2 The time will be longer in the magnetic pole detection of a linear servo motor and direct drive motor.
