Important
If soft-stop function is not required, it can be eliminated by setting P3708 to 1000.

11.8 OPEN LOOP JOYSTICK – TRANSFER FUNCTION
While using open loop joystick with PVED-CLS it is possible to define a transfer function, which scales the open loop
joystick position to a requested flow.
The transfer function configuration can be done by configuring the below parameters
•
The parameter P3734, i.e. AUX joystick - Maximum deflection region offset, defines the dead-bands at each
extremity of the transfer function.
•
Parameter P3736, AUX joystick - Dead-band region, which defines the dead-band around neutral position.
•
Parameter P3738 and P3740, i.e. Interpolation point X and Interpolation point Y respectively, to define the
slope from the neutral dead-band to the point
P (P3738,P3740) and from point P to the extremity dead-band on
positive side.
Similarly from the – (neutral dead-band) to the point
Q (-P3738, -P3740 ) and from point Q to the extremity
dead-band on negative side.
