Servo Amplifier
 

MR-J3-A : General-purpose interface

Pulse train and analog input are available as a general purpose interface. Position, speed or torque control mode can be selected. Machine’s performance can be boosted by using the optimum adjustment function such as advanced vibration control and adaptive filter .

 

MR-J3-B : SSCNET III compatible"

By adopting SSCNET III (optical communication), a complete synchronous system can be configured by using the high-speed serial communication with cycle time as fast as 0.44ms between the controller and servo amplifier. SSCNET III can be set up just by inserting a dedicated cable (optical-fiber cable) into connectors, resulting in reduced wiring and preventing possibility of wiring error.Thanks to the optical communication, noise immunity has been greatly improved, and long distance wiring is made possible by up to 800m (maximum of 50m between stations x 16 axes).Fully closed loop control compatible servo amplifier is also available (MR-J3-B-RJ006).

MR-J3-T CC-Link compatible (with built-in positioning function)

By setting position and speed data in the point tables in the servo amplifier, positioning operation is possible with a start signal from a host controller. Setting position and speed data in the point table, and start and stop operation are possible via CC-Link communication. By using  MR-J3-D01 extension IO unit, point table selection and positioning operation with DI/O commands are enabled. (CC-Link communication is not available when using the MR-J3-D01.)
