Product Description:

The FVCA01.2-0K40-3P4-MDA-LP-NNNN-02VRS frequency converter is produced by Bosch Rexroth Indramat in the FVCA Frequency Converters series and is part of line 01. This revision 2 unit belongs to frame size A and measures 125 mm in width, 122 mm in depth, and 275 mm in height, with a weight of 2.7 kg. It accepts three-phase mains at 3 AC 380 to 480 V with a tolerance of -15% to +10% and exchanges data through a ModBus interface. An onboard potentiometer and an LCD panel support local parameter entry, and the local controls allow operating values to be adjusted directly at the drive when needed.

The converter delivers an output power of 0.4 kW with a rated output current of 1.3 A, while drawing 1.6 A from the supply. A default carrier frequency of 8.0 kHz with SVPWM modulation helps reduce motor acoustic noise during operation. Digital frequency commands can be set in steps of 0.01 Hz, allowing fine speed adjustment for process control. In closed-loop FOC mode, the unit can provide a starting torque of 200 % at 0 Hz. It also supports V/f control and sensorless vector control, with a frequency accuracy of 0.05% of maximum in FOC mode and encoder-based speed regulation with a 1:1000 ratio. An integrated brake chopper works with an external braking resistor, and a relay contact rated 230 VAC / 30 VDC / 3 A is available for status signaling.

The power section is referenced to a nominal line of 400 V and supplies up to 0.8 kVA of apparent power across utility bands centered on 50/60 Hz. Its IP 20 housing is suited for indoor switchgear, and the integrated Class C3 filter helps limit conducted emissions in industrial areas. Continuous service is permitted up to 1,000 m above sea level. These ratings make the unit suitable for compact cabinet installations where controlled motor speed, local adjustment, and standard industrial communication are required.
