Product Description:

The Bosch Rexroth Indramat FVCA01.1-37K0-3P4-MDA-LP-P001-01V01 is a frequency converter in the FVCA Frequency Converters series. It controls the speed of three-phase induction and synchronous motors in automated machinery by converting fixed input frequency into a variable output through scalar or vector control methods. In drive systems, it supplies regulated torque and speed for conveyors, pumps, and positioning axes that must follow commanded process values.

An apparent power of 50.0 kVA supports a rated output of 37.0 kW when the unit is supplied from a three-phase 400 V line. Input demand reaches 88.0 A, and the motor output current is 75.0 A, which are the values used when sizing upstream protection and output wiring. The permissible mains range is 3 AC 380 to 480 V with a tolerance of -15% to +10%, and the output frequency can be adjusted in 0.01 Hz steps with 0.01% accuracy. V/f, SVC, and field-oriented control are available, and under field-oriented control the speed error remains within 0.05% while starting torque reaches 200% at 0 Hz. A PID loop and Modbus communication support integration with a PLC. The internal brake chopper uses an external resistor, the relay output is rated at 230 VAC or 30 VDC at 3 A, and SVPWM is used for output modulation.

Frame size E houses the electronics in an IP20 enclosure, and the converter can withstand overload conditions of 200% in 1 s / 150% in 60 s. A Class C3 EMC filter is included, and the carrier frequency is set to 3.0 kHz to help keep audible noise at a moderate level. With encoder feedback, the drive supports a speed control range of 1:1000 for positioning tasks. The housing measures 250 mm wide, 251.5 mm deep, and 525 mm high, and the unit has a mass of 22.0 kg. Status information is shown on the LCD, a single potentiometer provides manual trim, and the three supply phases connect through terminal points.
