BALDOR VS1SP AC Drive uses high performance control algorithms to allow control of induction motors using traditional a V/Hz control method or using sensorless vector control. It’s easy setup, quick startup, and right-out-of-the-box operation make it among the most popular variable speed motor controls.

Enhanced Software Performance:

  • Enhanced motor tuning featuring improved motor model. Accuracy improvement results in more torque per amp and the ability to control a wider range of variable speed motors
  • New power dip ride through uses the motor inertia to maintain bus voltage and power to the drive
  • Communication speed through put is increased by sending one data packet instead of multiple smaller pieces of information
  • Braking performance uses an improved regenerative torque limit calculation and results in more torque during deceleration
  • Motor current at zero speed is now selectable and can be set to output torque immediately after an enable input or to wait for a directional run command

Drive commonality is maintained within your facility for both closed loop and open loop applications by providing the same interface for all Baldor V*S Drives sensorless vector products.
