4. OPERATION AND FUNCTIONS
4.3 Operation from controller
The fully closed loop control compatible servo amplifier can be used with any of the following controllers.

HCPU/
Q170MCPU
Speed control (II) instructions (VVF and VVR) cannot
be used.
Positioning module QD74MH /QD75MH
An absolute type linear scale is required to configure an absolute position detection system.
The battery (MR-J3BAT) need not be fitted to the servo amplifier.
4.3.1 Operation from controller
Positioning operation from the controller is basically performed like the MR-J3-
B servo amplifier.
4.3.2 Servo system controller setting
When using fully closed loop system, make the following setting.
Set the other servo parameters and positioning control parameters as in the MR-J3-
B servo amplifier.
Parameter No.PA01, PC17, PC26, PC27, PE01, PE03 to PE05, PE34 and PE35 are written to the servo
amplifier and then are enabled using any of the methods indicated by
in Parameter valid conditions.
Parameter No.PE06 to PE08 are enabled at setting regardless of the valid conditions.
