The SV3000 Flux Vector Drives are digital AC flux-vector inverter drives designed to operate three-phase NEMA Design B induction motors on 380–460 VAC (±10%) supply power, using a DSP-based control platform with parameter-driven setup instead of potentiometers and jumpers.
They provide constant-torque performance over a wide speed range without feedback, and they can add an encoder interface for enhanced models to deliver tighter speed regulation down to zero speed and higher dynamic torque control. Standard operating features include keypad-based setup and monitoring on a backlit alphanumeric display, programmable analog and digital I/O, DC injection braking, and dynamic braking (built in on smaller ratings with external or factory-installed braking options for larger ratings). The drives include RS-485 serial communications for parameter access, control, and monitoring, along with diagnostics such as fault history/logging and multi-level security codes to restrict parameter changes. An optional “Shaft-Lock” software configuration supports synchronous serial master/follower architectures where a master can command multiple followers over an SCI network, with ratio control, trim adjustment, and position/speed lock behavior that requires enhanced-performance drives with encoders on each motor.
