ABOUT THE MANUAL
e-Manuals are Mitsubishi Electric FA electronic book manuals that can be browsed with a dedicated tool.
e-Manuals enable the following:
• Searching for desired information in multiple manuals at the same time (manual cross searching)
• Jumping from a link in a manual to another manual for reference
• Browsing for hardware specifications by scrolling over the components shown in product illustrations
• Bookmarking frequently referenced information
• Copying sample programs to engineering tools
If using the servo for the first time, prepare and use the following related manuals to ensure that the servo is used safely. The
manuals used differ depending on the interface of the servo amplifier. For details, refer to the User's Manual (Introduction).
This manual covers the following servo amplifiers.
• MR-J5-_G_/MR-J5W_-_G_/MR-J5-_A_
In this manual, the servo amplifier names are abbreviated as shown below.

2CONTROL MODE
2.1 Control mode [G] [WG]
The method for driving a servo motor varies depending on each control mode. The characteristics of each control mode are
shown in the following.
*1 Available on servo amplifiers with firmware version A5 or later.
*2 Available on servo amplifiers with firmware version B0 or later.
Control switching
In the motion mode, the control mode can be switched with [Modes of operation (Obj. 6060h)]. Switching the control modes
with [Modes of operation (Obj. 6060h)] applies to the cyclic modes (csp, csv, and cst), profile modes (pp, pv, and tq), homing
mode (hm), and continuous operation to torque control mode (ct).
Category Control mode Symbol Description
CiA 402 control mode Cyclic synchronous position
mode
csp This is a control mode to drive servo motors by receiving a position
command at a constant period in the synchronous communication with a
controller.
Use an absolute position address for the command.
Cyclic synchronous velocity
mode
csv This is a control mode to drive servo motors by receiving a speed
command at a constant period in the synchronous communication with a
controller.
Cyclic synchronous torque mode cst This is a control mode to drive servo motors by receiving a torque
command at a constant period in the synchronous communication with a
controller.
Profile position mode *1 pp This is a positioning mode to drive servo motors by receiving an end
position command via either synchronous or asynchronous
communication with a controller.
Use an absolute position address or a relative position address for the
command.
Profile velocity mode *1 pv This is a control mode to drive servo motors by receiving a target speed
command via either synchronous or asynchronous communication with a
controller.
Profile torque mode *1 tq This is a control mode to drive servo motors by receiving a target torque
command via either synchronous or asynchronous communication with a
controller.
Homing mode hm This is a control mode to perform homing with the method specified by the
controller.
Thrust/torque control Continuous operation to torque
control mode *2
ct This function enables smooth switching to torque control from the position
control mode or speed control mode without stopping the servo motor.
This eliminates rapid change of speed and torque, contributing to
reduction in load to the machine and high-quality product molding.
