3.5.3
Power ON Sequence
Consider the following points when you design the power ON sequence.
•
The ALM (Servo Alarm) signal is output for up to five seconds when the control power supply
is turned ON. Take this into consideration when you design the power ON sequence, and
turn ON the main circuit power supply to the SERVOPACK when the ALM signal is OFF (alarm
cleared).
•
Design the power ON sequence so that main circuit power supply is turned OFF when an
ALM (Servo Alarm Output) signal is output.
•
Make sure that the power supply specifications of all parts are suitable for the input power
supply.
•
Allow at least 1 s after the power supply is turned OFF before you turn it ON again.
Using a Spring Opener
Using a Flat-blade Screwdriver

screwdriver insertion hole to open the wire inser-
tion hole.
