The parameter specifies which method is used when the system runs upon the
hard limit. When it is set to 0, the system alarms and the motion axis decelerates
because the system runs upon the hard limit; when it is set to 1, the system
alarms and the motion axis stops suddenly and the coordinates are not same that
of the actual position because the system runs upon the hard limit.
Bit 1 0 automatic controllable spindle.
1 automatic uncontrollable spindle.
The system determines whether the spindle control is operated by pressing key in
AUTO mode.
Bit 0 0 spindle speed smoothness is invalid.
1 spindle speed smoothness is valid.
The parameter is used for thread cutting. Generally, when it is set to 0, it is benefit for
the system to trace the spindle speed. But with the extreme low speed to cut the
thread with extreme big pitch, it is set to 1, which is benefit to the stepper motor stably
running.

When the electric gear function is used with the different input and output unit, and the
backlash is measured by the system coordinate changing, the backlash can be input directly.
When the backlash is measured by the percentage form, the measured value should multiplex
the reciprocal of electric gear ratio. The coordinates of the trial-cutting toolsetting is also done so.
For example: Z electric gear ratio is 1:2, the measured Z dimension is 15mm, the input should be
KX2=30.
When the system uses the electric gear function, its max. speed and the output resolution will be
changed. When the electric gear numerator is more than its denominator, the permitted max.
speed will be reduced. Along with the electric gear ratio value changing, however the
relationship must be as follows:

× F ≤ 15000
The resolution output by the system is inverse proportion of the electric gear ratio value. The
bigger the electric gear ratio value, the smaller the system resolution is. Otherwise, the smaller
the electric gear ratio value is, the higher the resolution is.
To get the precise positioning and speed indicators, it is recommended that the electric gear ratio
is set to 1:1 and the actual electric gear ratio is set in the servo drive.
When the system is matched with the stepper drive, it is recommended that the drive unit with the
stepper division function is used, and as possible, the electric gear ratio is 1: 1 to avoid that the
difference between the numerator and denominator.
