176B8013 , Vari Speed® R400 Speed/Torque Control

The Vari Speed® R400 is a full-wave DC regenerative control that provides high performance four quadrant speed and torque control. The R400 solid state controller converts single phase AC line power into an adjust able DC power to control 1/4 to 2 horsepower DC motors.

The R400's flexible design is easily selectable for speed or torque mode, tachometer voltage, dual voltage and for horsepower size. The R400 is designed with today's most desirable features including isolated input signals, status indicators, alarm outputs. When performing frequent directional changes, the R400 trans fers excess system energy back to the AC line rather than wasting additional energy by the use of a dynamic brake resistor.

The R400 is designed, engineered and manufactured in the USA, and is UL and cUL listed.

Regenerative (Four- Quadrant) Control Regenerative DC drives are able to provide complete control of a DC motor's speed and torque simulta neously.A regenerative drive has the capability of producing torque in either braking or motoring modes, while operating a motor's speed in a consis tent direction of rotation. The capability to provide braking torque is a result of the drive's ability to operate in all four quadrants of the motor's speed/torque curve, as described in the example below.A four-quad DC drive's ability to operate in a regenerative mode is primarily provided by the additional power section included in the design. Four additional SCR devices are utilized in comparison to a standard NEMA Code K-type converter. These four additional components allow for the complete control of both the voltage and current flow to the armature of the DC motor, thus controlling both the speed and torque.

Quadrant I (Forward motor rotation forward torque) When the elevator is accelerating in an upward direction, the torque and speed are in the same direction.
Quadrant II (Reverse motor rotation forward torque) When the elevator is decelerating in a downward direction, the speed of the elevator is also going downward, but the torque is in the opposite direction and is braking the speed of the elevator. The motion energy from the elevator, motor and gravity are being regenerated back to the power line.
Quadrant III (Reverse motor rotation reverse torque) When the elevator is accelerating (faster than the gravity) in the downward direction, the torque and speed are in the same direction.
Quadrant IV (Forward motor rotation reverse torque) When the elevator is decelerating in an upward direction, the speed of the elevator is still going upward the torque is in the opposite direction and is braking the speed of the elevator. The motion energy from the elevator and motor are being regenerated back to the power line.
