10.7 Configuration of resolution, speed and acceleration

Before we start working, it is absolutely necessary to
set resolution (so-called scaling) of axes correctly and
to set their max. speed and acceleration -in the Mach3
program - „Config/Motor Tuning" menu. In the win-
dow, first select an axis you want to configure, next
enter parameters and click „SAVE AXIS SETTINGS". Now
you can select and set the next axis.
If we forget to click on „SAVE AXIS SETTINGS" all the changes will not be saved.
For correct axis scaling you must know how many steps falls on a unit (millimeter, inch or degree).
To understand how to calculate it, look at the example below:
• A linear axis is powered by servomotor with 10000 rpm encoder.
•
A servo drive is configured without a multiplier and a pulley, so the 10000 STEP pulses cause
a 1 rev of the motor.
•
To transfer the drive there was a ball screw used - pitch
•
No ratio between motor and a screw.
So there are 10000 pulses per motor rev and 10mm feed rate. Dividing these values 10000p/10mm
we get 1000p/mm value, which we enter into „Steps Per" box in configuration window.
In „Velocity" area, we set an axis speed. If we are using millimeters as an unit then speed is shown in
mm/min, if we use degrees - degree/min, if inch - inch/min. Max. speed value is very individual and
depends on what motors, drives etc. were used. For the first tests, we recommend to enter relatively
small value e.g. 2000mm/min, in case something went wrong, we will always have enough time to
press an emergency button E-STOP.
In „Acceleration" area, we define acceleration for an axis. At the beginning, we recommend to enter
something about 400mm/s
chine working.
Remember to click „SAVE AXIS SETTINGS" for each axis after finished edition. Perform the configura-
tion as follows:
Open „Motor Tuning" window Select axis („Axis Selection") Enter the parameters"SAVE AXIS
SETTINGS"Select the next axisetc. Click „OK" and close the window.
„Step pulse" and „dir pulse" areas do not matter for CSMIO/IP. They are used to control via LPT port
and they define width and STEP/DIR pulse time. The CSMIO/IP-S controller provides the signal with
the 50% duty cycle, which is the most optimal variant.

. Later you can set this parameter experimentally by assessing the ma-
