Product Description:

The Bosch Rexroth Indramat FVCA01.1-37K0-3P4-MNA-LP-P001-01V01 belongs to the FVCA Frequency Converters series and functions as a variable-speed drive component in multi-motor automation lines. As a frequency converter, it modulates the supply frequency delivered to standard induction machines, allowing closed-loop speed and torque control without mechanical gear changes. Its design lets OEMs integrate precise motor regulation into conveyor sections, pumps, or process fans that share a common three-phase bus in automated equipment.

Electrical ratings place the converter's continuous output at 37.0 kW, while the upstream network sees 50.0 kVA of apparent power. It is optimized for a nominal supply of 400 V and accepts three-phase lines from 380 to 480 V within the stated tolerance. Under those conditions, the drive draws 88.0 A and delivers 75.0 A to the motor, while an auxiliary relay switches 3 A logic loads. A 50 kHz digital output channel transmits high-speed status signals to external logic, and Modbus wiring provides parameter access. Local adjustments are made with the front-mounted potentiometer, and values are shown on an LCD. The unit is design revision 1, line 01, and release 01. No line filter is fitted, and the enclosure uses frame size E secured with M8 screws.

The drive uses a default carrier frequency of 3.0 kHz, and the flux-oriented control routine can produce startup torque of 200 % at 0 Hz. Closed-loop operation spans 1:1000 when an encoder is fitted, and encoderless vector control remains stable over 1:100. An external resistor is required for the brake chopper, and the heat sink trips at 85 °C to safeguard the power stage. The enclosure is rated IP 20, so the unit mounts inside a cabinet that can accommodate its 250 mm width, 251.5 mm depth, and 525 mm height. Net mass is 22.0 kg, and the aluminum body dissipates heat until thermal events trigger internal fault logic.
