15. ABSOLUTE POSITION DETECTION SYSTEM
15. ABSOLUTE POSITION DETECTION SYSTEM
CAUTION
If an absolute position erase alarm (AL.25) or an absoluto position counter marning
(AL.E3) has occurred, always perform home position setting again. Not doing so
can cause runaway.
POINT
When configuring an absolute position detection system using the QD75P/D
PLC, refer to the Type QD75P/QD75D Positioning Module User's Manual
QD75P1/QD75P2/QD75P4, QD75D1/QD75D2/QD75D4 (SH (NA) 080058).
15.1 Outline
15.1.1 Features
For normal operation, as shown below, the encoder consists of a detector designed to detect a position
within one revolution and a cumulative revolution counter designed to detect the number of revolutions.
The absolute position detection system always detects the absolute position of the machine and keeps it
battery-backed, independently of whether the general-purpose programming controller power is on or off.
Therefore, once the home position is defined at the time of machine installation, home position return is
not needed when power is switched on thereafter.
If a power failure or a fault occurs, restoration is easy.
Also, the absolute position data, which is battery-backed by the super capacitor in the encoder, can be
retained within the specified period (cumulative revolution counter value retaining time) if the cable is
unplugged or broken.

15.1.2 Restrictions
The absolute position detection system cannot be configured under the following conditions. Test
operation cannot be performed in the absolute position detection system, either. To perform test
operation, choose incremental in parameter No.1.
(1) Speed control mode, torque control mode.
(2) Control switch-over mode (position/speed, speed/torque, torque/position).
(3) Stroke-less coordinate system, e.g. rotary shaft, infinitely long positioning.
(4) Changing of electronic gear after home position setting.
(5) Use of alarm code output.
