For fullness setting the following functions are important:
Reference point adjustment after power On
After power On, the stepping motor runs in reverse direction until reaching the sensor. Then it runs in cw direction. After
leaving the sensor switching point, the steps set with parameter 002 and then the steps set on the control panel will be
performed in cw direction.
Reference point adjustment by means of pushbutton
After pressing a pushbutton connected to socket ST1/9, the reference point is adjusted in the same manner as after power On.
Parameter 131 = 0
After power On or pressing the pushbutton on input in7, the stepping motor runs in reverse direction
performing the steps set with parameter 002.
Parameter 131 = 1
The stepping motor runs in reverse direction until reaching the sensor (limit switch) on input in5 and then
switches to cw direction. Then the stepping motor stops immediately after leaving the sensor.
Parameter 131 = 2
Operation as with setting 1, however, after leaving the sensor, the stepping motor performs the steps set
with parameter 002 in reverse direction.
Parameter 131 = 3
Operation as with setting 1, after leaving the sensor, the stepping motor performs the steps set with
parameter 002 in cw direction.
Then after each of these settings, the stepping motor runs in cw direction performing the steps selected on the V810/V820
control panel.
Parameter 190 = 0
The pushbuttons on inputs in3 and in4 serve to increase or decrease the fullness values. Pushbuttons 1...0
on the control panel serve only to set the maximum values.
Parameter 190 = 1
The pushbuttons on inputs in3 and in4 are disabled. The fullness values are selected directly by means of
the pushbuttons on the control panel.
Parameter 274
Setting the maximum number of steps which can be performed in the fullness function without interfering
with the mechanism.
