Data unit : pulse/2 msec
Data range : 0 to 4095
Standard setting : 10
This parameter reduces speed fluctuations when aligning phase of
spindles in spindle phase synchronization control.
When this parameter is ”0”, since the phase alignment amount is only
issued once, the position deviation 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.

This sets velocity loop proportional gain in synchronization control. It
is selected HIGH when CTH1A=0 of input signal, and It is selected
LOW when CTH1A=1 of input signal.
