1. FUNCTIONS AND CONFIGURATION
The following items are the same as those for MR-J4-_B_. Refer to the section of the detailed explanation
field for details.
"MR-J4-_B_" means "MR-J4-_B_(-RJ) Servo Amplifier Instruction Manual".
"MR-J4-_DU_" means "MR-J4-DU_(-RJ)/MR-CR55K_ Instruction Manual".
1.1 Summary
MR-J4-_B_-LL (SSCNET III/H interface pressure control compatible servo amplifier) enables pressure
control using a pressure sensor (load cell).
The servo amplifier receives analog signals from the pressure sensor (load cell), and a servo system
controller gives a pressure command to the servo amplifier to control and maintain the actual pressure to
constant even if the load changes. This function is suitable for machines such as molding machines and
bonders which require pressure control.
Position control, speed control, and pressure control modes are available, and the mode can be changed
from the servo system controller.
Items not mentioned in this manual are the same as those for MR-J4-_B_ servo amplifier. Refer to "MR-J4-
_B_(-RJ) Servo Amplifier Instruction Manual" and "MR-J4-DU_(-RJ)/MR-CR55K_ Instruction Manual".
