is used to detect the position feedback signal of the load side encoder.
(b) In addition to the fully closed loop control that feeds back the position signal of the load side encoder, a
dual feedback control that feeds back a signal composed of the load side encoder's position feedback
signal and the motor position feedback signal has been added as an extended function.

Note. 1. Switching between semi closed loop control and fully closed loop control can be performed by changing the setting of
parameter No.PE01.
When semi closed loop control is selected, a control is always performed on the bases of the position data of the motor
encoder independently of whether the motor is at a stop or running.
2. When parameter No.PE01 "fully closed loop system" is valid, dual feedback control in which the motor feedback signal and
load side encoder feedback signal are combined by the dual feedback filter in parameter No.PE08 is performed.
In this case, fully closed loop control is performed when the motor is at a stop, and semi closed loop control is performed when
the motor is operating to improve control performance. When "4500" is set as the filter value of parameter No.PE08, fully
closed loop control is always performed.

time shortened.
If the motor side is at a stop, the side may be vibrating or the load side
accuracy not obtained.
Control is performed according to the motor side data during operation,
and according to the load side data at a stop in sequence to raise the gains
during operation and shorten the settling time.
A stop is made with the load side accuracy.
The load side accuracy is obtained not only at a stop but also during
operation.
Since this control is susceptible to machine resonance or other influences,
the gains of the servo amplifier do not rise and the settling time increases.

MR Configurator
High-resolution encoder of 262144 pulses/rev is used as a servo motor
encoder.
Merely setting a home position once makes home position return
unnecessary at every power-on.
You can switch between gains during rotation and gains during stop or use
an external signal to change gains during operation.
This function suppresses vibration at the arm end or residual vibration.
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Suppresses high-frequency resonance which occurs as servo system
response is increased.
Analyzes the frequency characteristic of the mechanical system by simply
connecting a servo configuration software-installed personal computer and
servo amplifier.
MR Configurator is necessary for this function.
Can simulate machine motions on a personal computer screen on the basis
of the machine analyzer results.
MR Configurator is necessary for this function.
Personal computer changes gains automatically and searches for overshoot-
