The block diagram above provides an overview of the construction of the ATV58 TRX drive controller power section. The drive controllers in the horsepower ranges referenced above are built in five frame sizes. (See the dimensional drawings on pages 120 to 122.) The various frame sizes share in common many components and technological advances:
•In frame size 1, the diode bridge section and the insulated gate bipolar transistor (IGBT) output section are integrated into one module. The dynamic braking module is purchased and mounted separately. All other frame sizes have the dynamic brake switching module internal to the product.
•In frame sizes 2 and 3, the diode bridge section, the IGBT output section, and the dynamic braking components are integrated into one module.
•In frame sizes 4 and 5, the diode bridge section is one module. The IGBT output section is integrated into a power module (PM). The dynamic braking transistor is incorporated into the diode bridge section or the power module, depending on the rating.
•The EMC filter is optional on frame sizes 3, 4, and 5.
Integration reduces the part count and the wiring and connection points required to connect components. The output section has fault detection and short circuit protection of the output transistors integrated into the module. The use of these modules eliminates individual gate drive cards and associated wiring as used by most other manufacturers in this horsepower range. These features combine to make the Altivar 58 TRX drive fit in a smaller package while improving the reliability of the product.
