SPECIAL FUNCTIONS-MOTOR TEST
The MOTOR TEST special function is used for ascertaining the
optimum speed settings. A window displays all parameters relevant
to the step calculation.
Motor test
The required values can be entered in the parameter boxes, after
which a test run can be performed immediately in order to check all
parameters.
Clicking the Move button causes WinPC-NC to move the selected
axis continuously forwards and backwards. By listening to and
observing the movement, it is easy to tell whether the parameters are
correct for the axis, or whether additional corrections are needed to
the speed or ramp length. The test run is cancelled by pressing the
(ESC) key or clicking the Stop button.
Optimum
parameters
The optimum values for an axis have been achieved if the motor
starts up quickly without step losses, and is still able to develop
sufficient torque at maximum speed.
Step -by-step
setting
Step-by-step procedure for testing X/Y and Z-axis :
1. Switch off the ramp length and slowly increase the start/stop speed
until the motor stalls. Then reduce the speed value by 30-40%.
2. Test the ramp length with various values. You have achieved a
good value if the motor starts up quickly without stalling.
3. Increase the rapid speed in stages. The motor should run quickly
while still developing sufficient torque.
Having ascertained the values, you can store them as parameters for
the axis in question. All parameters and their functions are explained
in a subsequent chapter.
