Spindle synchronous speed arrival level
Unit of data : 1min
-1
/sec
Valid data range : 0 to 32767
Standard setting : 10
For the synchronous speed command at spindle synchronous control,
if the error of the respective spindle motor speeds are within the
setting level, the spindle synchronous control complete signal
(FSPSY) becomes "1".
16i 30i
4034 4034
Shift amount at spindle phase synchronous control
Unit of data : 1 pulse unit (360 degrees/4096)
Valid data range : 0 to 4095
Standard setting : 0
Sets the shift amount from the reference position (one-rotation signal)
at spindle phase synchronous control.
16i 30i
4035 4035
Spindle phase synchronous compensation data
Unit of data : 1 pulse/2msec
Valid data range : 0 to 4095
Standard setting : 10
This parameter reduces speed fluctuations when aligning phase of
spindles in spindle phase synchronous control.
When this parameter is "0", since the phase alignment amount is only
issued once, the position error quickly becomes large, and there are
large speed changes on phase alignment.
It is possible to perform smooth phase alignments through issuing
separate commands for phase alignment amounts for the number of 2
msec pulses set in this parameter.

Velocity loop proportional gain on spindle synchronous control (HIGH)
CTH1A=0
4045 4045
Velocity loop proportional gain on spindle synchronous control (LOW)
CTH1A=1
Unit of data :
Valid data range : 0 to 32767
Standard setting : 10
This sets velocity loop proportional gain on spindle synchronous
control.
It is selected HIGH when CTH1A=0 of input signal, and It is selected
LOW when CTH1A=1 of input signal.
