Unidrive SP Regenerative Mode
Unidrive SP can be configured to provide full four-quadrant control of the power or drive system. In regenerative mode, the Unidrive SP is capable of either supplying power to the DC bus of the Unidrive controlling the motor or removing power from the DC bus of the Unidrive SP controlling the motor and returning it back to the supply.
•Unity or controllable input power factor
•Sinusoidal input current (low harmonic content)
Control Techniques engineers are experts at building four-quadrant regenerative systems for use in many applications where clean sinusoidal power can be put back to the AC supply.
Unidrive SP Regenerative Solutions
Servo Motor
Control Techniques has the solution for any application requiring pure sinusoidal regenerative output such as winder-to-winder or tensioner machines.
Positioning Using Closed-Loop Vector Motors
Unidrive SP motion programming platforms support closed- loop vector motor positioning applications using “Motion Made Easy,” PowerTools Pro software with the SM-EZMotion option module, or using SyPTPro with the SM-Applications option module. Many applications today can benefit from the advanced control capabilities, energy savings, cleanliness, noise reduction and advanced communications that AC vector motor positioning and the Unidrive SP can provide. Through its One Source program, Control Techniques offers a wide selection of closed-loop vector motors which feature an economical incremental encoder and matched cabling. This combination provides users with “plug-and-play” solutions for hundreds of applications that can now be solved using the latest AC motor and control technology to increase performance while lowering overall costs.
