Absolute encoder position-
pulses in a round or PUU
Communication address
：
037AH
037BH
Initial value
0x00
Control mode
ALL
Unit
Pulse or PUU
Configuration range
0 ~ (131072-1) (Pulse)
-2147483648 ~ 2147483647
(PUU)
Data size
32bit
Data format
DEC
If PD-57 Bit1= 1, the absolute coordinate is pulse value, the parameter represents the pulse in a turn.
If PD-57 Bit1= 0, the absolute coordinate is PUU, the parameter is encoder absolute position PUU.
