Description
The SU-BZR2 controller is designed to control the speed and direction of movement of various industrial and construction machines equipped with a hydrostatic transmission.
The SU-BZR2 provides the following functions:
-
Control of machine speed and movement direction
-
Maintaining the set rotation speed of travel drive hydraulic motors under changing loads
-
Synchronization of track speeds to maintain straight-line movement
-
Implementation of various drive operation modes (power, transport, and combined modes)
-
Maintaining the set speed and direction of movement
-
Prevention of overload and stalling of the internal combustion engine
-
Monitoring and self-diagnostics
The output power stages are protected against overcurrent, short circuits, and overvoltage.
