p W Control complex motions easily and precisely.
Combinations of four control modes achieve complex motion control. M Synchronized phase control and multiple machine control optimize any your machines.

Four Control Modes
►Synchronized Phase Control
►Torque Control
Generates a constant torque, regardless of speed.
(when using SVA-01A/-02A module)
(when using SVA-02A module) When T1 =T2
Speed control with position compensation (electronic shaft) or position control with 100% speed feed forward (electronic cam). Multi-axis servomotors can be controlled synchronously.

Applications of Synchronous Phase Control: Electronic Shaft, Electronic Cam
(when using SVA-01A/-02A module)
Because the mechanical systems for adjusting phases are no longer needed, the machine mechanism is much simplified, and no wear on parts results in improvement of position repeatability.
Electronic shaft
The AC servomotors move the same way as with rollers on the line shaft.

Cam curve definition
Set a curve at every block. (20 blocks max., 21 curves)
■Electronic cam
The AC servomotors move the same way as with the mechanical cam. Use the cam data generation tool for easy programming and adjustment.
Execution with MP920
The data list is processed in MP920. Motions of the machine can be monitored and adjusted with the following graphs.
•Cam graph (displacement)
•Control graph (speed, acceleration, saltation)
