N74050 Fine Positioning Dir.
The moving distance in fine positioning stage during returning to the machine
origin.
N74060 F in Fine Positioning
The feedrate in fine positioning stage during returning to the machine origin.
N74100 Lead Screw Pitch
It refers to the axial distance or degree between the corresponding points of
two adjacent teeth on the threads.
N74130/N74140 Mechanical Reducer Ratio
It is set to 1:1 by default.
m represents its numerator, while n represents its denominator, that is m/n.
The ratio of the input speed to output speed in mechanical reducer.
The ratio of the teeth number of driven wheel to that of driving wheel.
When applied in CNC machines, it specifies the ratio of motor speed to screw
speed.
2.4 Adjust the Axis Direction
This operation is used to check if the positive direction of each axis is the same with
the direction stipulated by Right Hand Rule, and adjust it if not, so as to avoid
damage to the machine tool due to incorrect direction.
Taking X-axis as an example, to check the axis direction, do the following:
1. Press → 2 → F8, input the manufacturer password, and check the
value of parameter N10000 Axis Direction(X):
– 1: positive
– -1: negative
2. Judge the positive direction of X-axis according to Right Hand Rule.
3. In JOG / Handle / Step mode, press X+ to move X-axis, and observe its moving
direction.
4. Optional: If the actual moving direction is opposite to the judged direction,
modify the value of parameter Axis Direction(X) to the opposite value.
Example
Current value of parameter Axis Direction(X) is 1. And you find X-axis moves
towards the negative direction by pressing X+.
Then, you need to change the value of the parameter to -1.
