16. FULLY CLOSED LOOP SYSTEM (available in the future)
16 - 17
16.3.3 Operation from controller
The fully closed loop control compatible servo amplifier can be used with any of the following controllers.
%CVGIQT[
/QFGN
4GOCTMU
Motion controller Q17nDSCPU
Simple motion module QD77MS_
Speed control (II) instructions (VVF and VVR) cannot
be used.
An absolute type linear encoder is necessary to configure an absolute position detection system under fully
closed loop control using a linear encoder. In this case, the encoder battery (MR-BAT6V1SET) need not be
installed to the servo amplifier. When an rotary encoder is used, an absolute position detection system can
be configured by installing the encoder battery (MR-BAT6V1SET) to the servo amplifier. In this case, the
battery life will be shorter because the power consumption is increased as the power is supplied to the two
encoders of motor side and load side.
(1) Operation from controller
Positioning operation from the controller is basically performed like the semi closed loop control.
(2) Servo system controller setting
When using fully closed loop system, make the following setting.
[[Pr.PA01], [Pr.PC17], [Pr.PE01], [Pr.PE03] to [Pr.PE05], [Pr.PE34] and [Pr.PE35] are written to the
servo amplifier and then are enabled using any of the methods indicated by ż in Parameter valid
conditions. [Pr. PE06] to [Pr. PE08] are enabled at setting regardless of the valid conditions.
