Electric two-position controls
The electric two-position control consists of an off/on-solenoid which acts on a two position, three-way
porting spool. Servo pressure is internally supplied to the two-position porting spool by an integral
system pressure shuttle.
De-energized = maximum displacement
When the solenoid is de-energized, the motor runs at maximum displacement. When energized, the
solenoid applies a force on the spool which ports high pressure to the larger diameter of the servo piston
and strokes the motor to minimum displacement. When the solenoid is de-energized, the motor strokes
back to maximum displacement.
De-energized = minimum displacement
When the solenoid is de-energized, the motor runs at minimum displacement. When energized, the
solenoid applies a force on the spool which ports the larger diameter of the servo piston to tank, and
strokes the motor to maximum displacement. When the solenoid is de-energized, the motor strokes back
to minimum displacement.

Only certain control options for the H1B motor use this electric two-position control. Please refer to the
motor’s nomenclature to determine if the motor is equipped with the proper option. You can find the
nomenclature on the motor’s nametag. For nomenclature details, refer to H1B Bent Axis Variable
Displacement Motors Technical Information, BC00000043.
