Note: Terminal L3 is not used for the single-phase 200 V, 750W SERVOPACKs. Do not connect.
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 is turned OFF when a servo alarm signal is output.
(See the circuit figure above.)
• The ALM signal is output for approximately two seconds when the power is turned ON. Take this into con-
sideration when designing the power ON sequence. The ALM signal actuates the alarm detection relay 1Ry
to stop main circuit power supply to the SERVOPACK.
• Select the power supply specifications for the parts in accordance with the input power supply.
