Denominator is the actual pulse equivalent, that is, the actual axis motion distance
corresponding to each position unit, or the system electric gear rate.
The unit of the external pulse equivalent numerator is micrometer (μm), and there is no unit
for the external pulse equivalent denominator.
External pulse equivalent numerator (μm)
Machine motion distance per motor revolution (μm)
External pulse equivalent denominator
Pulse sent by CNC per motor revolution
82
Appendix 1 Parameter Settings
Users may change the electric gear rate by setting the external pulse equivalent numerator
and the external pulse equivalent denominator, or change the motor rotation direction by
changing the positive or negative symbol (-, +) of the electric gear rate.
Example:
GK Series servo motor (2500 threads encoder) with HSV-16D driver; screw: 6 mm; gear rate:
2: 3
Then after each motor revolution, the CNC system will send 40000 pulses (quadruple
frequency for motor encoder and four-point subdivision for command, thus sent pulses =
2500*4*4=40000). The machine moves 4 mm (6 mm *2/3 = 4 mm), that is 4000 μm.
Therefore, the value of External Pulse Equivalent Numerator/External Pulse Equivalent
Denominator is 1/10 (4000/40000=1/10).
It is equivalent to set the External Pulse Equivalent Numerator to 1 and External Pulse
Equivalent Denominator to 10, or to set the External Pulse Equivalent Numerator to 2 and
External Pulse Equivalent Denominator to 20.

Description: The negative software limit point. This parameter value takes effect only after
the machine homes to the reference point.
y
REF Direction [machine factory]
Value: -, +
Description: The initial motion direction of axis to reference point after corresponding
reference command is sent. If users have pressed the button for homing the axis to the
reference point when the corresponding command is sent, the initial motion direction
83
Appendix 1 Parameter Settings
depends on the mode for homing to the reference point.
y
Reference Point Position [machine factory]
Unit: μm
Value: -2147483648 to 2147483647, default value: 0
Description: The coordinate position of the reference point in the machine coordinate system.

Therefore the reference point is generally set to 0.
y
Reference Point Offset [machine factory]
Unit: μm
Value: -32768 to 32767, default value: 0
Description: When homing to the reference point, after the axis reaches the Z pulse, the point
will not be defined as the reference point. The axis will continue to move a distance
specified by this value, and then the point will be defined as the reference point.
y
Rapid Traverse Speed at RER [machine factory]
Unit: Millimeter/Minute
(mm/min)
Value: 0 to 65535, default value: 500
Description: The rapid traverse speed before the reference point key is pressed.
Note: This value must be smaller than the maximum rapid traverse speed.
If this speed is set too fast, the distance between the reference point switch and nearby limit
switch (positive limit switch) cannot be too small. Otherwise, an over-limit alarm will be
reported and the system fails to home to reference point if the speed for homing to the
reference point is too fast to speed down and the limit switch is pressed.
In addition, the effective travel distance to the reference point cannot be too short, otherwise,
the system may fail to home to the reference point if the speed for homing to the reference
point is too fast to speed down before crossing the reference point.
y

y
Maximum Rapid Traverse Speed [machine factory]
Unit: mm/min
Value: 0 to 65535, default value: 1000
Description: The maximum rapid positioning speed of G00 (no processing) When the
override ratio of Rapid Traverse Speed reaches the maximum.
Note: The value of Maximum Rapid Traverse Speed must be the largest value among all
speed values of the axis. The value of Maximum Rapid Traverse Speed is very closely
related to the value of External Pulse Equivalent Numerator and External Pulse
Equivalent Denominator. You need to properly define this value to make sure the value
does not exceed the motor revolution speed range. For example, if the rated speed of the
motor is 2000 rpm, and connected to a ball screw that is six millimeter away from the screw
with a pair of synchronous gear belts whose gear ratio is 2: 3, then the maximum rapid
traverse speed cannot exceed 8000 mm/min (≤ 2000 * (2/3) * 6 = 8000).
y

Value: 0 to 800, default value: 64
Description: The time when the speed increases from 0 to 1 m/min or from 1 m/min to 0
during G00 positioning (no processing). The larger the time constant is, the slower the
acceleration and deceleration.
Note: This value depends on the motor size, the driver performance, and the load. It is
generally between 32 to 150. For example, the servo motor is generally 32 and the stepper
motor is 64.
y
Jerk for Rapid Traverse [machine factory]
Unit: ms
Value: 0 to 150, default value: 32
Description: The acceleration time constant during rapid traverse, which is generally 16, 32,

stepper motor is 32.
y
Positioning Tolerance [machine factory]
Unit: μm
Value: 0 to 255, default value: 20
Description: The maximum allowed positioning error.
Note: This value depends on the motor size, the driver performance and the load. The value
generally ranges between 10 and 50. If the value is too small, the system may not reach the
positioning tolerance value and stop the motor. If the value is too large, the processing
precision may be affected. Generally, the larger the machine is, the larger this value is. The
lower the machine transmission and precision is, the larger this value is.
If a stepper motor is used, it is recommended that you set the value to integral multiple of the
movement distance corresponding to each step.
y
Servo Type [machine factory]
Value: 45, 46, default value: 45
Description: Set this value to 45 for the servo motor that uses pulse interface with feedback.

Offset= machine command value - machine actual value
96
Appendix 1 Parameter Settings
The difference value between the actual value moved on the axis and the
command value, that is, the value the tool need to move further or less to make
the tool move to the accurate position on the axis.
For bidirectional pitch compensation, you need to enter correct positive pitch
offset value first, and then enter negative pitch offset value. The compensation
value (positive and negative) must be entered based on the position of the
compensation point in the machine coordinate system and based on the axis
direction. For example, for the two points (-150 and -100), you need to enter the
pitch offset value for -150 first and then for -100. In this case, the offset index
for -150 is on top of -100.
Example: If there are ten compensation points, and bidirectional pitch compensation is used,
then 0 to 9 are positive compensation values, and 10 to 19 are negative compensation.
Example:
If the command machine coordinate value is 100 mm and the actual machine coordinate
value is 100.01mm,then the offset is -10 μm (100 - 100.01 = -0.01mm = -10 μm).
You need to pay attention to the symbols of the axis value when calculating offset value. For
example, if the command machine coordinate value is -100 mm and the actual machine
coordinate value is -100.01mm, then the offset is 10 μm (-100 - (-100.01) = 0.01mm = 10
μm)
