M1, M2, K1, K2 Electric Proportional Controls for H1B Motors

Product overview

Electric proportional controls

The electric proportional control consists of a proportional solenoid which acts directly on a two-position, three-way porting spool. When activated, the solenoid pushes on the spool which then ports high pressure to the larger diameter of the servo piston. The servo piston and rotating group move to change the displacement to the point where the pressures on the servo are in balance with the force from the feedback spring.
De-energized = maximum displacement
With a de-energized to maximum displacement control, the de-energized proportional valve keeps the motor at maximum displacement. When energized, the solenoid pushes on the porting spool which moves to port high system pressure to the larger diameter end of the servo piston. Depending on the current supplied to the proportional valve, the motor will stroke between maximum displacement at zero current and minimum displacement at maximum current.
De-energized = minimum displacement
With a de-energized to minimum displacement control, the de-energized proportional valve keeps the motor at minimum displacement. When energized, the solenoid pushes on the porting spool which moves to port high system pressure to the larger diameter end of the servo piston. Depending on the current supplied to the proportional valve, the motor will stroke between minimum displacement at zero current and maximum displacement at maximum current.

Electric proportional with PCOR

In the de-energized state, the electric proportional control keeps the motor at minimum displacement until system pressure rises above the PCOR setting. When the PCOR activates, it ports high system pressure to the larger end of the servo piston, increasing the motor displacement to maximum.

Electric BPD

For propel applications, use the electric BPD option in conjunction with the PCOR option. The BPD shuttle valve is located ahead of the pressure compensator control valve.
The BPD consists of an electric off/on solenoid and a two-position, three-way porting spool. The applied logic allows the pressure compensator control to operate normally with high loop system pressure during acceleration and cuts off the supply pressure during deceleration if the motor is running in a pump mode (includes deceleration or overrun). This prevents rapid or uncontrolled deceleration while the machine is slowing down. With the BPD solenoid de-energized, the porting spool is centered by spring force.
The BPD solenoid must be controlled by a direction lever switch or an output signal from a micro­controller.
