„ Designing a Power ON Sequence
Note the following points when designing the power ON sequence.
• Design the power ON sequence so that main circuit power supply is turned OFF when a servo alarm signal
is output. See the previous circuit figure.
• The SERVOPACK will output (1Ry is OFF) a servo alarm signal for two seconds or less when the control
power is turned ON. This is required in order to initialize the SERVOPACK.
• Select the power supply specifications for the parts in accordance with the input power supply.
