Electronic gear ratio calculation formula = lead
screw pitch x 1000/(360 x subdivision number/
step angle x drive ratio)
5.1.2 Electronic gear ratio calculation method as
below,
(1) Set an electronic gear ratio, such as 8:1
(2) Run a command distance (the longer, the
more accurate), measure the real distance,
press F, input the command distance and
real distance, press F8 to automatically revise
current axis numerator/denominator.
5.1.3 Reference Null Point (reference zero point): program process start point, G92
automatically appears when running program, unit: mm (or inch)
5.1.4 Drawline offset: offset value of axis distance between draw-line torch and cutting torch
5.1.5 Reverse Backlash: because of machine’s reverse backlash, controller will compensate
backlash when change direction, backlash value is from measurement, unit: mm (or inch),
usually reverse backlash is not set.
5.1.6 Soft +/- limit: when coordinate is out of soft +/- limit, alarm, if not use, parameter
should be bigger than actual values, unit: mm (or inch)
5.1.7 Plate size: set plate actual size
1. gear numerator and gear denominator affect cutting size and speed
2. gear numerator is in principle bigger than gear denominator for bigger running speed
(1:1 has 0.001mm of control precision). When numerator is smaller than denominator, adjust
driver to make numerator bigger than denominator.
3. other parameters can choose according to the requests.
5.2 Enter Speed interface
5.2.1 Start Speed: controller’s start speed and stop speed of X axis and Y axis, unit: mm (or
inch)/min; jump frequency, machine makers set proper start speed according to machine
power, load and other factors. Usually there is no need to revise the parameter.
5.2.2 TimeMultiplyingPower (time multiplying power): multiplying power from start speed to
top speed limitation, value is bigger, acceleration time is longer
