Bosch Rexroth UPE2-1X/1, 1R0, 49/3A-1V+04100021 Part No. R901095988 Clamping and Drive Module Distribution

R901095988 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. The stator of the oil-immersed motor is pressed into the aluminum housing. It transfers the heat from the windings directly to the outer wall of the aluminum housing. For installation, four through-holes for mounting screws are provided at the bottom of the tank. The clamping and drive module operates in a vertical mounting position. The UPE 143 clamping and drive module can be optionally equipped with electronic monitors for oil level and oil temperature monitoring, air filters, and complete hydraulic control.

R901095988 Overview of accessory modules for clamping and drive modules

1) Basic module "G": – Basic module with integrated relief valve for simple lowering and holding 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 module 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 IH156A". Directional valve modules and seat valve modules can be combined!

R901095988 Features and applications of clamping and drive modules

Features: – Duty cycles: short-time duty S2 and intermittent duty S3. – Compact design. – Low noise. – Wide range of applications. – Diverse models. – Complete hydraulic control available (see catalog Clamping and Drive Modules). – Ready for connection. Applications: – Clamping, locking, releasing, and indexing on machines. – Driving hydraulic tools. – Driving lifting and swiveling equipment. – Use in general mechanical engineering. – Test machines and test benches. The specified component cleanliness levels must be observed in hydraulic systems. Effective filtration prevents failures and increases component service life. The clamping and drive modules are designed for short-time duty S2 and intermittent duty S3 operating modes within the nominal power range, in accordance with VDE 0530 (EN 60034) standards. The motor conforms to insulation class F, and the entire clamping and drive module conforms to protection class IP 96.

R901095988 Motors for clamping and drive modules

The clamping and drive modules are designed for short-time duty S2 and intermittent duty S3 operating modes within the nominal power range, in accordance with VDE 0530 (EN 60034) standards. 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). 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 "Act on Electromagnetic Compatibility of Equipment (Chapter 2, Section 4)" under the EEC directive, the clamping and drive module is not a ready-to-use device. To avoid potential electromagnetic interference, we recommend using interference suppression components manufactured by Murr-Elektronik of 71570 Oppenweiler. For example, type 23050, 3 x 400 VAC, 50-201 Hz. Terminal assignment: Terminal assignment in the terminal box on the clamping and drive module.
