Product Description:
The KDF 1.2-100-300-W1 is manufactured by Bosch Rexroth Indramat and belongs to the KDF Variable Frequency Drives series. It is an AC motor controller that adjusts output frequency to govern motor speed in automated lines, conveyors, and pump groups. By varying the electrical output delivered to a connected motor, the unit helps match mechanical throughput to process demand and reduce energy use in industrial automation. This operating method also supports smooth speed changes and steady running in applications that do not require servo-level position feedback. It is well suited to process sections where speed must track a commanded value and load changes remain within the normal range of induction motor control.
This drive is classified as an Variable Frequency Drive (Open-Loop), so it regulates motor speed without closed-loop feedback from a transducer. Internally it operates on a 300 VDC DC link, so the upstream rectifier or shared bus must maintain that level during load changes. A continuous phase current of 100 A indicates the motor amperage the power stage can supply during normal operation. Field wiring lands on Bus Connector X1, which has 16 poles, and the enclosure has an overall length of 500 mm to accommodate the power section and DC-link components. This connector arrangement groups external wiring in one interface, which can simplify cabinet layout and control-signal routing.
The enclosure is 140 mm high and 380 mm wide, which helps it fit panel layouts with limited mounting space. The unit has a mass of 15 kg, so the mounting surface should support that static load during operation. Its output stage is intended for a General Purpose Induction Motor, allowing use with common industrial motor frames. Panel layouts should also allow service access at the connection points and enough clearance for heat to move away from the power section. The stated dimensions help installers plan spacing around adjacent components without changing the intended motor application.
