Product Description:

Bosch Rexroth Indramat manufactures the FECG01.2-4K00-3P400-A-SP-MODB-01V01, a variable-speed AC drive within the FEC Frequency Converters series. It is intended for general automation where matching motor speed to changing load conditions improves throughput and energy use. By converting fixed line frequency into a programmable output, the device lets conveyors, pumps, and small process machines run exactly as fast as each task requires.

The converter delivers a continuous output of 10 A, enough to support induction motors up to 4.0 kW. It accepts supply lines in the range of 3 AC 380 to 480 V and uses V/F control so voltage rises proportionally with commanded frequency. Output steps are issued in increments of 0.01 Hz, and the speed regulation range is 1:100, allowing low-speed operation without auxiliary gear reduction. Eight digital inputs, three analog inputs, and two analog outputs accommodate local sensors and potentiometers, while a single RS485 port running Modbus provides communication with PLCs. Magnetic flux PWM ensures smooth waveform synthesis, and the internal brake chopper manages surplus DC-bus energy during rapid deceleration.

The drive withstands momentary overloads of 200% for 1 second and prolonged surges of 150% for 60 seconds, and its start-up torque reaches 150% at 5 Hz so heavily loaded shafts can break static friction without mechanical clutches. Protection class IP20 suits cabinet installation in clean electrical rooms, while the small front panel with an integrated potentiometer simplifies manual jogging during local operation. Design 2 electronics are housed in a mechanical size 1 frame that measures 125 mm wide, 176 mm deep, and 220 mm high, leaving cabinet space for contactors or filters. Three-phase input terminals are located on the upper edge, so cables route directly to busbars and keep wiring compact inside enclosures.
