Speed governor
HCB-MSC (Engine Speed Control)

Depending on the parameterization, the speed governor controls or regulates the speed of a hydraulic motor.

An analog value (from a higher-level controller) or a frequency signal (speed) can serve as the setpoint source. A trimming factor can be continuously adjusted between the setpoint and actual speed.

The standard hardware for this control system is the HCB controller, which can be used to control 2 solenoids. The MSC control unit enables unidirectional control of a pump.

If it is necessary for the speed governor to interact with another function, it is easy to port the function to another hardware platform. One example is the synchronization of a winch with a traction drive for off-road vehicles or with a cylinder function (davit in shipbuilding).

The speed governor is used in speed-dependent spreading material application (feed and fertilizer spreaders and winter service), in the synchronization of conveyor belt drives, etc.

Inputs and outputs

• Digital input for release, manual mode switchover
• Frequency inputs for the set and actual speed of the hydraulic motor
• Analog inputs for the trimming factor or setpoint specification in manual mode
• Proportional output with current feedback measurement for a proportional valve
• Status outputs for fault diagnosis
