5.2.1 Emergency Run Function If Machine Select Is Invalid
If the control cannot identify an admissible value for the machine select resistor, only emergency run functions are possible.
All parameter settings and preset values are preserved.

5.3 Positions
Functions Parameter
Setting the reference position (Sr1) 170
Setting the signal and stop positions (Sr2) 171
Display of the signal and stop positions (Sr3) 172
The angular positions necessary on the machine, e.g. for “needle down position” or “thread lever up position”, are stored in
the control as numerical or angular values. In order to establish a relationship between electrical position transmitter
information and actual mechanical position, a reference position is needed.
5.3.1 Setting the Reference Position
The angular positions necessary on the machine e.g. “needle down position“ or “thread lever up position“ are stored in the
control. A reference position is needed in order to establish a relationship between position transmitter information and
actual mechanical position.
The reference position must be set:
for initial operation
after replacing the position transmitter
after replacing the microprocessor
Reference position = Needle point at the height of the needle plate, from downward movement of the
needle in the direction of rotation of the motor shaft.
Note
If a different needle position (other than reference position) is set, the values of the signal and stop positions (Pos1 and
Pos2) preset by the manufacturer are no longer valid and must be reset.
5.3.2 Setting the Reference Position on Control Panel V810
Select parameter 170.
Press key E.
Press key >> (B).
Turn handwheel until desired reference position is reached.
Note: Turn at least until marker [ ] has disappeared!
Press key E.
Reference position is entered.
