SP150 CPDT
C-axis control zero point
return deceleration point
This parameter is valid when SP129 (SPECC)/bitE is set
to "0".
Set the deceleration rate where the machine starts to
decelerate when it returns to the target stop point during
C-axis zero point return.
When the machine tends to overshoot at the stop point,
set the smaller value.
1 to 10000 1
SP151 CPSTL
C-axis zero point return
shift amount (low byte)
0000
SP152 CPSTH
C-axis zero point return
shift amount (high byte)
This parameter is valid when SPECC (SP129)/bitE is set
to "0".
Set the C-axis zero point position.

SP156 OVSH
C-axis control overshoot
compensation
Set this to prevent overshooting when shifting from
movement to stopping with C-axis control.
(Set this referring to the load meter display when
overshooting occurred.)
