ORIENTATION CONTROL—A500(L)
(4) Pr. 361 "position shift". (factory setting: 0)
The stop positions are those defined by the position command plus the value set in Pr. 361.
<Position shift function>
Shifts the origin according to the compensation value without changing the origin of the position
detector (encoder).
3.5.2
Internal stop position command
(1) Pr. 356 "internal stop position command" (factory setting: 0)
Setting "0" in Pr. 350 "stop position command selection" chooses the internal position command mode.
In the internal position command mode, the value set in Pr. 356 is the stop position. When the encoder
pulse count is 1024prr, one revolution of the encoder (360 degrees) is divided into 4096 positions, i.e.
360 degrees/4096 pulses = 0.0879 degrees/pulses per address, as shown below. The stop positions
(addresses) are indicated in parentheses.
REMARKS
When the FR-A5AP is fitted and Pr. 350 "stop position command selection" is set to make orientation control valid, the
PU (FR-DU04/FR-PU04) shows the rotation direction of the encoder.
Make setting so that FWD is displayed when the STF signal turns on or REV is displayed when the STR signal turns on.
