The Rexroth IndraDrive FCS frequency converters are three-phase AC motor drives intended for asynchronous motors, using a voltage/frequency control approach and an available sensorless current vector control mode to improve starting behavior and speed regulation under load.
The series is rated for typical industrial mains supplies in the 230 V and 400/480 V classes and covers a broad output-power range, with an output frequency adjustable from 0 to 400 Hz to suit standard motors and high-speed spindles. FCS converters integrate core drive functions such as automatic motor parameter identification, a built-in PID process controller, programmable DC braking, ramp shaping, a flying-restart function, and basic signal recording for commissioning and troubleshooting. Hardware integration includes serial communication interfaces and a practical I/O set, with optional fieldbus interfaces available for networked control.
