DIRCT2-DIRCT1:
Rotation direction at orientation
DIRCT2 DIRCT1 Rotation direction
0 0
Depends on the previous rotation direction
(counterclockwise for the first rotation after power–up)
0 1
Depends on the previous rotation direction (clockwise
for the first rotation after power–up)
1 0 Counterclockwise viewed from the motor shaft
1 1 Clockwise viewed from the motor shaft
PCMGSL: Choice of orientation method
0: Position coder method
1: Magnetic sensor method
Specify: 0
PCPL2, PCPL1, PCPL0, PCTYPE: Position coder signal setting
Specify these bits according to the detector type. (When using a
position coder, specify 0,0,0,0.)

NRROEN RFCHK4
6517 3017 3017 4017
RFCHK4: Position coder one–rotation signal detection function in normal
rotation
0: Not provided
1: Provided
If this bit is set to 1, the orientation time after rotation at a speed
exceeding the maximum speed of position coder signal detection
(Parameter No. 4098) can be reduced.
NRROEN: Shortcut function for orientation specified from the stop state
0: Not provided
1: Provided
If this bit is set to 1, the shortcut function is used when the following
conditions are satisfied:
i) Bit 7 (RFCHK3) of parameter No. 4016 is set to 0.
ii) Speed zero detection signal SST, which is a output signal, is
set to 1.
iii) Shortcut command NRROA, which is a input signal, is set to
1.

DTTMCS: Dead–zone compensation in Cs contouring control and high–speed
orientation
