System Configuration

Feature

Avoidance of slip effect during high-speed operation and stop

Fully Closed Control

High response and high precision by combining motor side and load side encoder for positioning

In operation: servo motor side, In stop: Position control by switching to machine side encoder. High gain setting becomes possible. The settling time is shortened and the influence of the slip of the driving section is eliminated, enabling high-precision positioning control.

How to Configure Full Closed Control

By using Engineering tool MELSOFT GX Works3 fully closed control electronic gear setting for the servo parameter of axis 1.

Multi wheel drive control

Master/Slave operation

Multi-axis torque sharing operation with position command for one axis

Since the MR-J4-B can transmit the same torque data from the master axis to the slave axis through driver communication, multi-axis torque sharing operation is possible

Setting of master/slave operation

Set servo parameters corresponding to master and slave axes with engineering tool MELSOFT GX Works3.

Fast start-up

Function Blocks

Program simplification by using function blocks (FB)

With the unit FB of MELSOFT GX Works3, motion control such as positioning control and advanced synchronization control can be programmed easily.

Programming with Function Blocks

With engineering tool MELSOFT GX Works3, you can create a program simply by dragging and dropping the necessary FB from the unit FB or registered FB provided on FA site to the editor screen.
