Product Description:

The FVCA01.1-7K50-3P4-MDA-LP-P002-01V01 is a frequency converter from Bosch Rexroth Indramat that belongs to the FVCA Frequency Converters series. It is designed to modulate three-phase 400 V induction or permanent-magnet motors in automated machinery, using V/f, SVC, or FOC control to match speed and torque demands without mechanical gear changes. An integrated LCD, a front-panel potentiometer, and Modbus connectivity give machine builders both local and networked adjustment of acceleration profiles and braking, while the built-in brake chopper dissipates regenerated energy during fast stops.

The drive supplies up to 11.0 kVA of apparent power and delivers a continuous output of 17 A, enough for motors rated at its nominal 7.5 kW output power. Internally, the IGBTs switch at a default carrier of 8.0 kHz, balancing acoustic noise with switching losses. For brief overload events, the current ceiling rises to 200% In (1 s), allowing rapid acceleration of heavy inertial loads. Acceptable mains inputs range from three-phase 380 to 480 V (-15% / +10%) at 50/60 Hz, and line disturbances are attenuated by the Class C3 RFI filter. The unit's relay terminal can switch 230 VAC or 30 VDC at 3 A for fault or run status signaling. Rated input current is 23.5 A, and motor frequency can be ramped up to 400 Hz across a 1:100 speed span without an encoder.

An IP20 housing, frame size B, and dimensions of 330 × 150 × 157 mm (H×W×D) make the converter suitable for cabinet installation where ambient air stays below +40 °C and above -10 °C. Closed-loop feedback widens the velocity window to 1:1000, supporting precise positioning tasks. Start-up torque reaches 200% at 0 Hz, so conveyors or extruders can move from rest under full load. Reliable service is maintained up to 1,000 m altitude and 90% relative humidity, and the total mass is 4.9 kg, easing panel mounting during build or retrofit.
