Product Description:

The FECP02.1-30K0-3P400-A-BN-MODB-01V01 is an AC drive from Bosch Rexroth Indramat in the FEC Frequency Converters series. This second-generation, design 1 unit serves pump and fan automation by converting a fixed three-phase 400 VAC supply into adjustable output while remaining housed in an IP20 enclosure. It is intended for variable-speed applications where motor output needs to follow changing process demand rather than run at a constant mains frequency. The unit uses size 4 mechanics, a large front panel, and a 290 mm width that simplify cabinet layout, and its 21.5 kg frame can be mounted up to 1000 m where ambient conditions stay between –10 °C and +40 °C with humidity below 90%.

Input power enters on a three-phase 380 to 480 V AC supply within the 50–60 Hz mains range. The inverter provides 30 kW of rated output while delivering a continuous 60 A motor current through V/f control, which supports a 1:100 speed range for gradual process changes. An external brake chopper diverts excess DC-bus energy during deceleration. Carrier pulses shape output from 0 to 599 Hz, and the ModBus interface passes operating data to higher-level controllers. For short overload events, the converter tolerates 120% for 60 seconds, and digital setpoints are required because the front panel has no potentiometer.

Extended demand periods are handled by an additional reserve of 105% for 60 minutes, which helps the drive maintain regulation when auxiliary equipment increases load. High breakaway requirements are covered by a startup torque of 150% at 5 Hz, enabling centrifugal pumps to overcome static friction at low speed. Command resolution reaches 0.01 Hz, which helps smooth low-speed adjustment during flow-control changes. Switching devices operate within a selectable 1 to 8 kHz PWM band, allowing a balance between acoustic noise and thermal stress.
