POINT
In the super trace control, droop pulses are near 0 during the servo motor
control. Thus, the normal INP (In-position) may always be turned on. Be sure to
set "INP (In-position) on condition selection" in [Pr. PD31] to " _ 1 _ _".
When you use the super trace control, it is recommended that the acceleration
time constant up to the rated speed be set to 1 s or more.
The following shows the adjustment procedure.
