Power-On/Servo Control-Ready [S-Rdy] - Fuji Electric Alpha7 VV User Manual

 If the keypad does not light up
Appropriate voltage (200 [V]) is not supplied to the control power terminals (L1C and L2C). Check
the source voltage.
In case of three-phase 400 [V], use a transformer to drop to 200 [V] to supply. (400 [V] will
damage the servo amplifier.)

If two characters from the left is "AL. " an alarm is detected. In this case, the display blinks.
If the keypad shows those other than specified above, the servo amplifier is not in the factory
shipment state.
