Product Description:

Bosch Rexroth Indramat manufactures the FVCA01.2-0K75-3P4-MDA-LP-NNNN-02VRS as part of the FVCA Frequency Converters series. It belongs to series line 01 and design revision 2. The converter operates from a three-phase supply to control the speed of induction motors in automated machinery. An LCD display supports local parameter viewing, while Modbus connectivity provides remote commands. A panel-mounted potentiometer allows direct manual adjustment of setpoints when simple speed trimming is needed, and this arrangement lets the unit be controlled either from the front panel or through a networked control system.

The converter has a nominal input rating of 400 V and operates across a 3 AC 380 to 480 V range with a tolerance of -15% to +10%. It provides motor output of 0.75 kW, draws up to 3.7 A, and supplies 2.5 A to the load. Its apparent power requirement is 1.6 kVA. The default 8.0 kHz carrier uses SVPWM and supports V/f, SVC, or FOC control with PID regulation for different motor-control modes. An integrated brake chopper manages regenerated energy, and an external resistor can be connected when braking duty is high. The input is compatible with 50/60 Hz power, the relay output can switch 230 VAC or 30 VDC at 3 A, and the unit meets industrial environment class C3 limits for conducted emissions.

With field-oriented control, torque can reach 200% at 0 Hz during startup. Speed holding accuracy is kept within 0.05% of the maximum frequency, and parameter increments as small as 0.01 Hz allow fine speed adjustment from the keypad. The LCD and keypad support very small setpoint changes without relying on a separate analog reference. The converter uses frame size A and measures 125 mm wide, 122 mm deep, and 275 mm high. Its mass is 2.7 kg, and the enclosure has an IP20 rating for cabinet-mounted installation.
