Datasheet
334 Servo system
Single-phase, 230 VAC (100 W to 750 W models)
*1. There is no polarity on the brake.
*2. For 750 W servo drive, B2 and B3 are short-circuited. If the internal regenerative resistor is insufficient, remove the wire between B2 and B3 and connect an
external regenerative resistor between B1 and B2.
*3. There is no internal regeneration resistor for 100 to 400 W models. When the amount of regeneration is large, connect the necessary regeneration resistor
between B1 and B2.
*4. To use a DC reactor, remove the short-circuit wire and connect the DC reactor between N1 and N2.
Note: The input functions of pins 12 to 15 and 32 to 35, and output functions of pins 9 to 11 and 29 to 31, can be changed via parameter settings.
