Bosch Rexroth UPE2-1X/1, 1R5, 25/4AT-B1V+04100987 Part No. R904100989 Clamping and Drive Module Distribution
R904100989 Bosch Rexroth UPE 2 clamping and drive modules constitute a complete drive system that is ready for connection upon delivery. They are used to supply hydraulic oil to the hydraulic circuit. Due to thermal load considerations, the clamping and drive modules operate in short-time duty and intermittent duty modes. The duty cycle is selected based on power output and environmental conditions so that the maximum permissible operating temperature of 80 °C is not exceeded. The clamping and drive module basically consists of an aluminum housing, a pump (radial piston pump or external gear pump), and an oil-immersed motor.

R904100989 Overview of accessory modules for clamping and drive modules
1) Basic module "G": – Basic module with integrated relief valve for simple lowering and holding pressure functions. – If basic module "G" is used, further stacking is not feasible. – For more details, see catalog "Control block types for clamping and drive modules. IH15A". 2) Directional valve module "W" 1): – Allows control designs using valves with porting surfaces conforming to DIN 24340 form A. – The number of directional valve modules depends on the discharge volume and pump displacement. – For more details, see catalog "Control block types for clamping and drive modules IH15A". 3) Seat valve module "S" 1): – The basic composition of a seat valve includes: • One relief valve block. • One or several control blocks. • One end block. – Control is designed according to the specific application. – The number of seat valve modules depends on the discharge volume and pump displacement. – For more details, see catalog "Control block types for clamping and drive modules IH73A". Directional valve modules and seat valve modules can be combined!
R904100989 Commissioning instructions for clamping and drive modules
– Please check whether the clamping and drive module has been professionally connected (hydraulically and electrically) to the machine to be operated. – For the electrical connection of the motor, the washers and connection bridges included in the delivery scope must be used. – The motor must be protected by equipment with an overload relay. The latter must be set to the nominal current indicated on the nameplate/tag. – When installing the clamping and drive module on an external gear pump, the direction of rotation of the motor must be strictly observed; see the arrow indicating the direction of rotation. (Practical check: Briefly switch on the motor and check whether the pump can transfer fluid.) (Visual check: Remove the air filter on the tank cover, briefly switch on the motor, and check the direction of rotation of the rotor shaft.) – Hydraulic oil may only be filled through a filter with the required minimum retention rate. – The clamping and drive module must be filled with hydraulic oil to the maximum level, until the oil gauge reaches the lower edge of the cover. – Under no circumstances should the clamping and drive module be operated without hydraulic oil.
R904100989 Motor for clamping and drive modules
The clamping and drive modules are designed for operation in short-time duty S2 and intermittent duty S3 modes within the nominal power range, in accordance with standard VDE 0530 (EN 60034). The motor conforms to insulation class F, and the entire clamping and drive module conforms to protection class IP 54. The direction of rotation of the motor depends on the installed pump (see "Technical Data" on page 4 for this point). Motor technical data Voltage 1) U V 230 / 400 ±6 % Δ/Y. Frequency f Hz 50 / 60. Operating mode S2 short-time duty, S3 intermittent duty. Insulation class F (windings). Protection class IP 54. Number of poles 2 / 4. Electromagnetic compatibility of the equipment (EMVG): According to the provisions of the "Act on Electromagnetic Compatibility of Equipment" under the EEC directive (Chapter 2, Section 4), the clamping and drive module is not a ready-to-use device. To avoid possible electromagnetic interference, we recommend using interference suppression components manufactured by Murr-Elektronik of 71570 Oppenweiler. For example, type 23050, 3 x 400 VAC, 50-118 Hz. Terminal assignment: Terminal assignment inside the terminal box on the clamping and drive module.
