R911298766
The R911298766 (HMD01.1N-W0036-A-07-NNNN), a power module crafted by Bosch Rexroth Indramat, is part of the esteemed HMD product line up and is designed to fit into the IndraDrive M series drive controller. To ensure optimal operation, the unit must be safeguarded against intrusion by foreign materials or liquids. High housing voltage and leakage current are common during operation, while faulty components or erroneous cable connections may lead to hazardous movements. An integral cooling system, comprising of a circulating air blower, keeps the device cool. The R911298766 (HMD01.1N-W0036-A-07-NNNN) module boasts of a 2*68nF nominal Y-capacitance and offers a steady output current of 13A at 8kHz and 20A at 4kHz.
Keeping the module's optimal functioning in mind, it is designed to tolerate a maximum ambient temperature of 55°C at reduced nominal data and requires a minimum of 80mm clearance on top and 100mm at the bottom. Special attention should be taken while connecting the module to the motor, using shielded motor power cables. It operates at a DC bus voltage in the range of 254VDC to 750VDC. Ensure the module is placed at least 400 mm away from magnetic elements in a control cabinet, with the X6 connector enabling motor temperature monitoring. The product has a load time constant of 50ms and a switching frequency of 0.5Hz. It uses connection cables with a cross-sectional area between 0.5mm2 and 1.5mm2.
