Power ON Sequence
Consider the following points when you design the power ON sequence.
•
The ALM (Servo Alarm) signal is output for up to three seconds when the power supply is
turned ON. Take this into consideration when you design the power ON sequence, and main-
tain the power-up status until the ALM signal turns OFF (alarm cleared).
*
This example is for the connection diagram on the next page.
•
Design the power ON sequence so that the power supply input to the SERVOPACK is turned
OFF when an ALM (Servo Alarm) signal is output.
CAUTION
Wire all connections correctly according to the following table.
There is a risk of SERVOPACK failure or fire if incorrect wiring is performed.

WARNING
Even after you turn OFF the power supply, a residual voltage may still remain in the SERVO-
PACK. To prevent electric shock, do not touch the SERVOPACK after you turn OFF the
power. When the voltage is discharged, the PWR indicator will turn OFF. Make sure the PWR
indicator is OFF before you start wiring or inspection work.
