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).
