Bosch Rexroth UPE2-1X/2, 2R1, 70/7A-T1V+R901161730 Part No. R901166653 Clamping and Drive Module Distribution

R901166653 Bosch Rexroth UPE 2 clamping and drive modules constitute a complete drive system that is ready for connection upon delivery. It is used to supply hydraulic oil to the hydraulic circuit. For reasons related to thermal load, the clamping and drive module will 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 will operate in a vertical mounting position. Optionally, the UPE 175 clamping and drive module can be equipped with electronic monitors for oil level and oil temperature monitoring, air filters, and complete hydraulic control.

R901166653 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 the 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 IH188A". Directional valve modules and seat valve modules can be combined!

R901166653 Commissioning instructions for clamping and drive modules

– Start the clamping and drive module under no-load conditions and let it run at zero pressure for a few seconds to ensure adequate lubrication. – After draining the hydraulic oil by moving the hydraulic controls and actuators back and forth several times or by opening available bleed points, refill the hydraulic oil in the clamping and drive module to the correct level. – The clamping and drive module must only be operated within the permitted limits. Operate the module only when there are no disputes. – When performing any work on the clamping and drive module, the system must be depressurized and de-energized. – No conversions or modifications that could affect safety and functionality may be carried out without authorization. – Existing protective devices must not be dismantled. – Generally applicable safety regulations and accident prevention regulations must be observed. Caution! During operation, the clamping and drive module becomes hot => risk of injury! The clamping and drive module may only be set up, maintained, and repaired by authorized, trained, and instructed personnel. Only original spare parts may be used during repairs!

R901166653 Motor for clamping and drive modules

The clamping and drive module is designed for short-time duty S2 and intermittent duty S3 operating 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). 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 EEC directive "Act on electromagnetic compatibility of equipment (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, 50-233 Hz. Terminal assignment: Terminal assignment in the junction box on the clamping and drive module.
