Function Code Parameter Name Display Range
U0-38
ABZ position 0 to 65535
U0-38: It displays phase A and B pulse counting of current ABZ or UVW encoder. This value is
four times the number of pulses that encoder runs. For example, if the display is 4000, actual
number of pulses that encoder runs is 4000/4 = 1000.
The value increases when encoder rotates in forward direction and decreases when encoder
rotates in reverse direction. After increasing to 65535, the value restarts to increase from 0. After
decreasing to 0, the value restarts to decrease from 65535.
You can check whether installation of encoder is normal by viewing U0-38.
Function Code Parameter Name Display Range
U0-39
Target voltage upon V/F separation 0 V to rated motor voltage
U0-40
Output voltage upon V/F separation 0 V to rated motor voltage
U0-39 and U0-40: They display target output voltage and current actual output voltage in V/F
separation status.
