Product description
Heidenhain 387852-01 identifies the UM 115D inverter power module. The device assignment is one axis or one spindle within a modular HEIDENHAIN inverter system. At a PWM frequency of 5 kHz, rated current is 96 A for axis operation and 125 A for spindle operation. The associated maximum current is 192 A. Heat is dissipated internally through the enclosure and its ventilation structure. A motor holding-brake connection is present. A diagnostic function and electronic ID label are also part of this version. The front contains the power and control connections, and module width is 150 mm. The complete dimensional drawing gives a height of 480 mm, depth of 300 mm and housing width of 149 mm with a 1 mm upper tolerance. Complete external dimensions are therefore stated as 480 × 300 × 150 mm in height × depth × width order. Manufacturer weight is 19.0 kg. The power module has an IP20 protection rating and a cabinet-mount enclosure. Identification number 387852-01 and designation UM 115D identify the specific version. Further classification features include internal heat removal, single-axis or single-spindle operation and the current ratings at 5 kHz. The separate height, depth and width figures are 480, 300 and 150 respectively. The module grid, overall height, full depth and mounting tabs form the complete device envelope. External dimensions and weight appear as the final two specification rows.
