To control the elevation position, the Drive uses the following input signals:
A travel limit microswitch which defines a zero-reference position, acquired by the machine
during its power-on reset procedure and whenever the microswitch is pressed. The travel
limit microswitch outputs a normally closed signal which becomes open when the
microswitch is pressed.
ATTENTION: when the travel limit microswitch outputs an open contact signal
(pressed, microswitch broken or cable interrupted), the downward movement of the
machine is disabled.
If the Drive detects problems with these signals during operation of the elevation motor, i.e.:
If it has not received any pulses during a previously defined time interval.
If, when the travel limit microswitch outputs an open contact signal, this contact does not
switch to closed when the elevation motor moves upward by a distance of 2%.
Then:
The drive stops functioning with error code "EdC"
The machine displays the "ELEVATION ERROR" message, and interrupts the exercise.
The parameter Par 07 is switched to 1 to disable the elevation function.
At this point the machine will only allow movements of the tread belt motor, but not of the
elevation motor. To re-instate operation of the elevation motor, the machine must be turned off and
on again, so as to automatically reset Par 07 to 0.
If the problem persists, the machine will again show the elevation error on the Display.
3.15.3. R
ESET PROCEDURE
On power-up, the machine performs a reset procedure in order to determine the zero-reference
position for the elevation movements. The machine makes a downward movement until the travel
limit microswitch is pressed, and then moves upward by the number of pulses (100 pulses) defined
in the elevation table to reach the reference "horizontal position". All the movements for reaching
different elevations will be variations relative to this reference.
