The VS1SP AC Drive uses a traditional inverter V/Hz control method. Its easy setup, quick startup, and right-out-of-the-box operation make it among the most popular variable speed motor controls. It is ideal for applications where multiple motors are operated simultaneously from one motor control, including pumps, fans, and general machinery applications.
For single motor operation, the VS1SP drive is also encoderless, which allows better speed and current control for high-performance, open-loop applications. Available in horsepowers from 3/4 to 250 HP and voltage ranges from 180-660 volts, these drives incorporate a variety of features and design innovations that ensure dependable performance.
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.

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
