Backlash Compensation
The controller includes a procedure for compensating for
backlash on the ETS valve spindle. The parameters involved in this
procedure are listed below
Compensation value for spindle play at valve's closing point (number of steps)
Compensation value for spindle play during operation (number of steps)
Valve definition
1=Valve must open when more capacity is required (NC function)
2=Valve must close when more capacity is required (NO function)
Compensation direction
1=Compensation takes place when the valve opens (normal setting)
2=Compensation takes place when the valve closes
These parameters should not be changed and the reason the
parameters are accessible is only historical, and at some point will
be withdrawn from the menu.
