Standard setting: 0 0 0 0 0 0 0 0
RFCHK4:
Specifies whether to use the position coder 1-rotation signal detection
function in normal rotation
0: Does not detect the 1-rotation signal in normal rotation.
1: Detects the 1-rotation signal in normal rotation.
PC1CAT:
Specifies whether a position coder one–rotation signal is detected
during spindle orientation by a magnetic sensor.
0: Not detected.
1: Detected.
NRROEN:
Specifies whether the shortcut function is used when spindle
orientation by a position coder is performed from the stopped state.
0: Not used.
1: Used.
When this bit is set to 1, the shortcut function is used when the
following requirements are satisfied:
D Bit 7 (RFCHK3) of parameter No. 4192 is set to 0.
D The speed zero signal SST is set to 1.
D The shortcut command NRRO is set to 1.

SSTTRQ:
Specifies whether to use torque clamping at speed of 0
0: Uses clamping.
1: Does not use clamping.
SDTCHG:
Specifies whether to switch from the high–speed range to low–speed
range upon the speed detection signal (SDT) being set to 1 when
output switching is used.
0: Switches regardless of the speed detection signal (SDT).
1: Switches when the speed detection signal (SDT) is set to 1.
VDCV1: Specifies whether DC link voltage detection filter processing is
performed.
0: Performed. (Normally set to 0)
1: Not performed.
