change of the pumps the rate of change of the motor can also be different depending on the direction of transition for example for a predictable linear response it is desirable for the motors to change displacement at the same rate as the pump during acceleration however during deceleration as shown in fig7 at p 5 the power source may only be able to absorb a limited amount of negative power and is an advantage when the pump reduces displacement that the motor increases displacement at a slower rate than the pumps to allow the hydrostatic system to absorb more of the braking energy instead of transmitting it to the power source when the pump effectively becomes a motor thus in fig6 is shown a scheme for the motor displacement change which occurs based on pump lever position thus as shown the first part of the adjustment p 1 and p 2 is not operator adjustable but set in the control program to be some arbitrary set point s as shown at say 30 between 0 and 100 of the pump lever setting the operator is however able to adjust as shown at sel the motors minimum limit from 0 motor maximum displacement to something less than 100.
