Electronic open and

closed loop speed control for hydraulic drives

RE 95300/12.07

Replaces: 04.04

Features

Hydraulic drives are often operated on diesel engines whose

speed in operation cannot be kept constant due to different

driving proﬁles.

The electronic open and closed loop speed control is an easily

conﬁgurable software application for the open and closed loop

control of hydraulic drives. It is used to keep the output speed

constant independently of diesel engine and pump speeds.

Three variants are available:

– Variant A for open loop speed control (SPCA)

– Variant C for closed loop speed control (SPCC)

– Variant D for closed loop speed control in concrete mixer

vehicles (SPCD)

The open and closed loop speed control is designed for use with

Rexroth hydraulic pumps.

The user can easily conﬁgure the open and closed loop speed

control for various combinations of pumps, combustion engines,

sensors and equipment.

The open and closed loop speed control is suitable for diesel

engines with or without a CAN bus interface (SAE J1939

protocol for SPCA).

Diagnostics and parameter settings are performed with the

BODAS service PC software.

Open and Closed Loop Speed Control SPC Bosch Rexroth AG RE 95300/12.07 /16 Variant SPCC The electronic closed loop speed control (Speed Control, SPCC) is an easily configurable software application for the closed loop control of hydraulic drives. Here, the hydraulic drive consists of a pump and one or more hydraulic motors. The closed loop speed control serves to keep the drive speed constant, independent of the speeds of the diesel engine and the pump.

In case of an error or if the safety switch is actuated, the drive is turned off immediately.

Open and Closed Loop Speed Control SPC Bosch Rexroth AG RE 95300/12.07 Variant SPCD Functional Description The electronic closed loop speed control (Speed Control, SPCD) is an easily configurable software application for the closed loop control of hydraulic drives in concrete mixer vehicles. The hydraulic drive here consists of a pump and a hydraulic motor. It is used to turn the drum of the concrete mixer vehicle.

Open and Closed Loop Speed Control SPC Bosch Rexroth AG RE 95300/12.07 When the button used to select the direction of rotation is pressed once more, the drum starts to move again. The drive uses the stored speed and direction of rotation. This takes place with an adjustable time ramp. The time ramp for the memory function is set at the same time as the time ramp for the stop function. If the other button is pressed, the stored speed and direction of rotation are erased.
