Product Description:
The Bosch Rexroth Indramat KDF 1.2-100-300-W1-220 belongs to the KDF Variable Frequency Drives series. It is installed as a speed-regulating element in industrial automation where precise motor control is required for conveyors, winders, and positioning axes. The drive is intended for placement inside a control cabinet, allowing centralized wiring and thermal management while operating with upstream PLC commands to vary motor frequency and voltage. This arrangement keeps the power electronics and control connections in one enclosure, which supports orderly cable routing and stable system integration.
This model delivers a continuous output of 100 A and draws power from a regulated DC bus held at 300 VDC. Heat generated by the power stage is expelled through a blower-cooled channel so the unit can sustain rated current without derating. Velocity is managed by a digital velocity loop that samples feedback rapidly and applies corrective action through pulse-width modulation. Command logic is exchanged over a parallel interface that supports 16 command bits, permitting direct start, stop, jog, and fault-reset functions from the system controller. For process control tasks that use proportional speed demands, the inverter also accepts an analog velocity command signal, converting the ±10 V reference into a real-time torque request.
The drive reaches a maximum speed of 8000 RPM, allowing the connected motor to accelerate quickly during indexing or traverse cycles. Its output is matched to a nominal 25 HP motor, aligning the power stage with medium-frame induction or synchronous machines used in packaging and textile equipment. When fixed throughput rates are needed, the drive offers an unlimited 4-speed mode that stores four discrete frequency presets and allows on-the-fly selection through binary inputs. This setup lets the controller switch between preset operating points without relying on external analog scaling hardware.
