4. OPERATION

(4)Outline of absolute position detection data communication

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.

(5) Battery installation procedure

Before starting battery installation procedure, make sure that the charge lamp is off WARNING more than 10 minutes after power-off. Then, confirm that the voltage is safe in the

tester or the like. Otherwise, you may get an electric shock.

POINT

The internal circuits of the servo amplifier may be damaged by static electricity. Always take the following precautions:

Ground human body and work bench.

Do not touch the conductive areas, such as connector pins and electrical parts, directly by hand.
