Func
tions
V2 Control Mode Selection
Select a control method in V2 control mode selection P012.
When "00" (ASR) is selected in P012, speed control mode is enabled. Select a frequency reference
in frequency reference selection A001.
When "01" (APR) is selected in P012, the Inverter enables position control by generating frequency
reference based on the position command pulse input from the pulse train position command input
terminal, and on the position feedback detected by the encoder.
Select any of the three pulse train position command input modes in pulse train mode selection
P013.
To perform pulse train position control, allocate "48" (STAT) to any of the multi-function input termi-
nals. While the STAT terminal is tuned on, pulse train position command input is accepted.
Position deviation can be cleared through external input. Allocate "47" (PCLR) to any of the multi-
function input terminals. Tuning on and then off the PCLR terminal can clear position deviation data.
Allocate "22" (DSE) to any of the multi-function output terminals to enable excessive speed devia-
tion signal output.
Set a deviation level in speed deviation error detection level P027. When the deviation between real
frequency and reference frequency exceeds the P027 set value, the DSE signal turns on.
When "02" (APR2) or "03" (HAPR) is selected in P012, the Inverter performs absolute position con-
trol with reference to the absolute position from its origin.
