Motor parameters
X/Y/Z/U axle parameters
Direction Polarity
: Modification of direction polarity can move the motor to the
opposite direction. The modification purpose can move this axle to the origin on resetting. If
this axle moves far from the origin on resetting, it means the direction polarity of this axle is
wrong in setting and should be modified.
Spacing Polarity
: it is used to set the high and low level mode of spacing signal. When
the motion axle arrives at the spacing position and input a low-level signal to the mainboard,
the spacing polarity at this time should be set to be minus.
scope
: it means the farthest distance that the motion axle can move, which is
determined in accordance with the actual condition of the machine.
Distance from Origin to Hard Spacing
: if this axle enables hard-spacing protection,
generally this value should be set to be 2~5mm; if it is set to be 0, when this motion axle moves
to the smallest coordinate, i.e. 0, this spacing may be validate, which may wrongly triggers the
hard-spacing protection and scram the machine. If the hard-spacing protection is not enabled,
this value can be set to be 0~5mm.
Control Mode
: Double pulse or disingle pulse are optional, in general,
disingle pulse is selected.
Motor Stepping
: it means the impulse equivalent, the absolute distance gone by the
corresponding motion axle when a pulse is delivered to the motor. Prior to the correct setting
of this value, a large rectangle can be cut with the machine (the larger the figure is, the smaller
the difference is). The motor stepping can automatically be calculated according to the figure
length and measuring length.
Hard-spacing Protection
: it is used for whether the hard-spacing protection of this
axle is enabled.
PWM Rising edge valid
：
To set the motor driver
’
s pulse signal rising edge valid or
falling edge valid. If this item is disabled, the pulse is falling edge valid, or, it
’
s rising edge valid.
Reset Enable
: if the machine is provided with this axle, its
“
Reset Enable
”
should be
opened; if no, its
“
Reset Enable
”
should be prohibited.
Takeoff Speed
: it means the speed of the motion axle 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
axle is larger (the axle is heavier), you can set a smaller takeoff speed; if smaller (the axle is
lighter), you can increase the takeoff speed. For example, the typical value is 5~30mm/s.
Maximum Speed
: it means the maximum limit of motion speed that this axle can bear.
This parameter has something to do with the driving force of motor, the inertia of motion axle
and its drive ratio. For example, the typical value is 200~500mm/s.
Maximum Acceleration
: it means the maximum acceleration of the motion axle 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
