16.3.8 Absolute position detection system under fully closed loop system
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 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 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.
For the absolute position detection system with linear encoder, the restrictions mentioned in this section
apply. Enable the absolute position detection system with [Pr. PA03 Absolute position detection system] and
use this servo within the following restrictions.
(1) Using conditions
(a) Use an absolute type linear encoder with the load-side encoder.
(b) Select Always fully closed loop ([Pr. PA01] = _ _ 1 _ and [Pr. PE01] = _ _ _ 0).
(2) Absolute position detection range using encoder
Encoder type
Absolute position detection enabled range
Linear encoder
(Serial Interface)
Movable distance range of linear encoder (within 32-bit absolute position data)
(3) Alarm detection
The absolute position-related alarm ([AL. 25]) and warnings (AL. 92] and [AL. 9F]) are not detected.
