DIRCT1, DIRCT2 Rotation direction at spindle orientation
DIRCT2 DIRCT1 Rotation direction
0 0
By rotation direction immediately before (CCW for the
first-time spindle orientation after the power is switched on)
0 1
By rotation direction immediately before (CW for the
first-time spindle orientation after the power is switched on)
1 0 CCW direction looking from shaft of motor
1 1 CW direction looking from shaft of motor
PCMGSL : Orientation method selection
Set this bit to 1 (magnetic sensor method).

when bit 2 (SPDUNT) of parameter No. 4006 is set to 1)
Valid data range : 0 to 32767
Standard setting value : 0
This data is used to set an orientation speed at the spindle end.
If this data is set to 0, an orientation speed is determined from the
position gain and the motor speed limit ratio in orientation.

Velocity proportional gain on orientation (HIGH) CTH1A=0
3043 4043 4043
Velocity proportional gain on orientation (LOW) CTH1A=1
Unit of data :
Valid data range : 0 to 32767
Standard setting value : 10
This data is used to set the velocity loop proportional gain on spindle
orientation.
When the input signal CTH1A = 0, (HIGH) is selected. When the
input signal CTH1A = 1, (LOW) is selected.
