2. Wiring and connection
2-16
In case of FDA7004, connect AC220V to power terminal “r, t” of control circuit
according to model. Be sure to check the power specification of the model.
(Note3) In case of FDA7004 ~ FDA7010 model, regenerative resistor is installed inside servo
drive. In case of For FDA7015-7150 and FDA7020-H~7750-H, the regenerative resistor
must be installed externally. In case of FDA7075 ~ 7150, FDA7075-H ~ 7750-H, please
contact our sales office because regenerative resistance is sold separately.
(Note4) Be sure to ground the ground wire of CN1 cable to FG (Frame Ground) terminal.
2.4.2. Timing chart of power
The timing of servo drive operation can be checked according to the power on / off and
SVONEN input contact status. Check the operation timing when wiring the power and brake.
