2.4.1. Wiring
If you turn the power on and off frequently, the peripheral elements of the main circuit will
deteriorate because a large charging current (charging time 0.3 to 0.5 seconds) flows when the
main power is turned on. Therefore, be sure to use STOP contact for motor operation and stop,
and SVONEN contact for emergency stop.

(Note1) A noise filter (NF) must be installed to block noise from the outside and to protect the
servo drive peripherals.
(Note2) In case of FDA7001~7002, it is not necessary to connect power to the power terminals
"r, t" of the control circuit.
In case of FDA7004~7150, connect AC220V to power terminal “r, t” of control circuit.
