Product Description:

Bosch Rexroth Indramat manufactures the FECG01.2-11K0-3P400-A-BN-MODB-01V01, a drive in the FEC Frequency Converters series. This unit is a frequency converter intended for general automation tasks where variable motor speed is needed from a fixed three-phase supply. It belongs to the first-generation design and incorporates U/f control with an internal brake chopper to manage regenerated energy. Communication with higher-level controllers is handled through a ModBus interface, allowing direct integration into distributed control architectures.

The converter is designed for a voltage class of 400 VAC, allowing connection to industrial mains within the three-phase 380–480 V range. Its continuous output rating reaches 11 kW, providing sufficient power for medium-sized pumps, fans, or conveyors. On the supply side, the drive draws up to 30 A, while the inverter section can deliver 24 A of current to the motor terminals; these values support proper cable sizing and protective device selection. Closed-loop speed commands can be set with a frequency resolution of 0.01 Hz, permitting fine incremental adjustments at low and nominal speeds. These values indicate the drive’s operating range and support precise motor speed adjustment.

For transient loads, the converter can withstand 200% for 1 second of its rated current and a sustained margin of 150% for 60 seconds, which helps accommodate heavy startups or brief process jams without immediate tripping. Analog reference inputs are tracked to a precision of 0.05%, supporting accurate speed matching when multiple drives share a common process line. The housing carries an IP20 protection class, indicating finger-safe access while still requiring installation inside a control cabinet. At 10.7 kg and 220 mm wide, the size 2 frame fits standard panel layouts, and the large operator panel provides local parameter access.
