igin Offset if this axis enabled hard limit protection (Page 73 / 76) RDWorks V8 Laser Engraving Cutting Software User Manual

Origin Offset: if this axis enabled hard limit protection, it should be 2~5mm. If set 0, the axis

moves to the min. coordinate 0, which might make the limit effective, so will trigger the hard limit

protection wrongly and the machine will stop urgently. If disable hard limit protection, the value

can be set 0~5mm.

Control Mode: Double PWM and direction + single pulse are optional; it is configured with the

motor driver types. In general, direction + single pulse is selected.

Motor Stepping: it means the impulse equivalent, the absolute distance by the corresponding

motion axis when a pulse is delivered to the motor. Prior to the correct setting of this value, a

larger rectangle can be cut by the machine (the larger the graphic is, the smaller the error is). The

motor stepping can automatically be calculated according to the graphic length and measuring

length.

Hard limit/spacing Protection: it is used for whether the hard-spacing protection of this axis is

enabled.

PWM rising edge effective: apply to set the pulse signal of motor driver. When this option cannot

be enabled, the falling edge effective; this option enabled, the rising edge effective.

Reset Enable: if the machine is configured this axis, “Reset Enable” should be opened; if no,

“Reset Enable” should be prohibited. This parameter is mainly to control the “Reset Enable”

option in user parameters and “axis reset” in function keys, to prevent user to reset one axis which

is not exist in real.

Jump-off Speed: it means the speed of the motion axis in direct start from the idle condition. If

this value is excessively large, it will make the motor lose steps, jar and even squeak; if small, it

will reduce the running speed of the whole figure. If the inertia of the motion axis is larger (the

axis is heavier), you can set a smaller jump-off speed; if smaller (the axis is lighter), the jump-off

speed can be increased. For example, the typical value is 5~30mm/s.

Maximum Speed: it means the maximum limit of motion speed that this axis can bear. This

parameter has something to do with the driving force of motor, the inertia of motion axis and its

drive ratio. For example, the typical value is 200~500mm/s.

Maximum Acceleration: it means the maximum acceleration of the motion axis in accelerated or

decelerated motion. If the acceleration is set too large, it will make the motor lose steps, jar and

even squeak; if too small, it will cause the reduction of acceleration so as to reduce the running

speed of the whole figure. For the axis with larger inertia, such as Y axis corresponding to the

beam, its typical setting range is 800~3000mm/s2; for the axis with smaller inertia, such as X axis

corresponding to the car, its typical setting range is 8000~20000mm/s2.
