The open loop transfer function applies for all open loop joysticks and allows joystick flow request scaled to the internal
resolution, using piecewise linear conversion, based on slope values defined by parameters P3734 to P3740, of the scaled
joystick position limited by following rules-
•
P3734 i.e. ‘ AUX joystick-Maximum deflection region offset’ is less than or equal to (1000 IR – P3738 i.e. ‘ AUX
joystick-Interpolation point X for open loop joystick transfer function’ ).
•
P3740 i.e. ‘ AUX joystick - Interpolation point Y for open loop joystick transfer function’ shall be greater than 0
and less than or equal to 1000 IR.
•
P3736 i.e. ‘ AUX joystick - Dead-band region ’ shall be less than or equal to P3738.
PVED-CLS will enter safe state if these rules are not followed.
