A06B-6050-H402 - Velocity Control Unit - FANUC

The AC servo unit consists basically of the velocity control unit and power transformer. In addition, the separate regenerative discharge unit may be required according to the load conditions.
Eight types of velocity control units are available according to AC servo motor models employed, and one velocity control unit applies to each servo motor.
Six types of power transformers are also prepared according to the servo motor models, theirs combinations, loads, and primary input voltages.
One power transformer applies to one to three servo motors.

The Ac servo unit for 2 axes consists of the velocity control unit and power transformer. Three types of velocity control units are available according to the combations of AC servo models employed. One velocity control unit applies to two servo motors. The speccifications of the power transformer are the same as those of a power transformer employed when two servo units for one axis are used according to the combinations of motor models.

The AC servo servo unit for 3 axes consists of the velocity contorl unit, the power transformer and the discharge unit.
Four types of velocity control unit are available according to the combinations of the AC servo motor models employed.
One velocity control unit applies to three servo motors.
One power transformer is employed according to the combiantions of motor model.
A regenerative discharge unit is a resistor unit which consules the regenerated energy by the motor.
If the AC servo motor models employed are rather small type having a little regenerative energy, a regenerative discharge unit may be necessary.
