Potentiometer Now Available On SMVector Inverters

Lenze-AC Technology Corporation announces the release of the Potentiometer Option for SMVector NEMA 4X Inverter models. According to company sources, the Potentiometer option is built right into the terminal cover, providing direct front panel access. Steve Dextraze, Inverter Product Manager at Lenze-AC Tech, calls it robust and easy to maneuver and states that the potentiometer knob takes the place of the up/down buttons on the drive keypad, giving the operator manual speed control over a 0-10V analog output.

"The potentiometer option is great for use in hands-on applications where speed must be ramped up/down, such as conveyer applications or food/beverage process applications." says Dextraze, adding, "In single use installations the potentiometer provides just the right amount of control without the user having to use the keypad."

Dextraze explains that the SMVector inverter drive provides all the features required by demanding applications, including four modes of operation - V/Hz, Enhanced V/Hz, Vector Speed, and Torque - plus high starting torque, auto-tuning, advanced low-speed control and dynamic speed regulation. Dextraze further comments that the SMVector is designed to be truly a global product, with an input voltage ranging from 120VAC 1-phase to 600 VAC, 3-phase, plus The Electronic Programming Module or EPM, a removable chip that is the drive's memory and allows a customer to program multiple drives in just seconds; the SMVector NEMA 4X also offers an integral disconnect option for quick and easy motor maintenance.

Lenze-AC Tech develops, manufactures, markets and supports a complete range of motion control solutions, including servo drives and motors, clutches and brakes, gears and gear motors and variable frequency AC motor drives. Lenze-AC Tech's portfolio of AC Drive products extends from some of the world's smallest sub-micro drives up through large, 500 HP. With North American headquarters in Uxbridge, Massachusetts and a global network of distributors and representatives, Lenze-AC Tech is perfectly positioned to meet the motion management needs of customers throughout the world.

Positionservo Now Available With ISO 13849 Safety Circuit

Lenze-AC Tech announces the release of the ISO 13849-1 Safety Circuit for the PositionServo drive. PositionServo drives with suffixes "ES" and "RS" now include a safety circuit that disables the drive output to the motor so that the drive cannot generate torque in the motor. This safety function, termed "Safe Standstill", meets the requirements of ISO 13849-1 Safety of machinery - Safety-related parts of control systems - Part 1: General principles for design. The PositionServo ISO 13849-1 safety circuit provides a highly reliable disable of the drive. Even in the event of a single fault (single component failure) the ISO 13849-1 safety circuit will still function and disable the drive.

ISO 13849-1 takes up where EN954 was lacking in addressing safety circuits in programmable electronic systems. ISO 13849-1 uses probability to define performance levels in terms of category (structure), mean time to dangerous failure (MTTFd), diagnostic coverage (DC) and common cause failure (CCF). Fully characterizing these four parameters provides a clearer picture of the level of performance required for the safety circuit to disable the device in which it is installed.

"Lenze-AC Tech drives are employed in many types of automated processes worldwide and the safety of both the equipment and personnel is paramount." says Dale Seidlitz, Quality and Safety Manager at Lenze-AC Tech. "Designing our products in accordance with the strict requirements of international safety standards just makes it easier for our global customers to purchase our products, knowing we have designed safety into them." The ISO 13849 safety circuit provides the customer with one more safeguard to protect his investment in automation equipment and personnel.

Perfectly Pair Servo Drives & Motors, With New MotionMatch Software

Lenze-AC Tech announces the release of the MotionMatch sizing software for its servo drives and motors. Company officials describe the combination of MotionMatch Motor Sizing & MotionView Drive Configuration Software as a powerful yet simple solution to motion control management. According to Darrow Hanesian, Director of Product Management at Lenze-AC Tech, "Sizing a motor shouldn't be rocket science and neither should programming a servo drive." Hanesian states that Lenze-AC Tech's MotionMatch, used with the existing MotionView, takes all the guess work out of pairing a PositionServo drive and a Lenze Servo motor, plus the user can now configure the drive with infinite ease.

"Our application engineers often get asked about the right size motor for a customer's application; unfortunately, however, the question usually comes after some failure has occurred" says Hanesian. Deb Kling, Lenze-AC Tech Marketing Manager, agrees, "With thousands of drive and motor combinations to choose from, it is no wonder that customers get frustrated with the selection process; with MotionMatch, all you need to do is enter your application requirements and the program will return the compatible servo drive-motor combinations." Hanesian and Kling say that Lenze-AC Tech customers have been using MotionView to configure the PositionServo drive since the software's introduction in 2001. "The success of MotionView lies in its intuitive Windows-based platform and the ability to fully program the drive from a PC," says Hanesian.

Control Techniques Extends Unimotor fm Range Of Servo Motors

Control Techniques have extended their Unimotor-FM servo motor range up to a massive 136 Nm. The extension is based on a 250mm frame size, encompassing three models with 92, 116 and 136 Nm continuous stall torque and nearly doubles the available power rating of the existing FM range. Using in house developed computer aided motor design software Control Techniques has produced a high torque, low cogging motor ideal for smooth low-speed performance, the 250 frame models all feature a high peak torque (408Nm for the biggest), giving potential cost benefits over other servo-motors. With 480V operation, all three motors have been designed, from the outset to provide a perfect match to the characteristics and performance of The Unidrive SP AC drive. A range of feedback options include resolver, encoder and Sin/Cos with connections via a hybrid box or a power connector available as an option.

With an exceptionally rugged construction, strong bearings and shaft strength, giving rigidity and stiffness even with powerful radial and axial loads, the 250 frame offers exceptional performance and accuracy even in the most demanding of applications. "We believe that we have the best performing big servo on the market today," says Managing Director Keith Hedges. "The design incorporates many features to make the designer's and user's lives easier, including easy swap-out with competitors' motors - the same shaft, the same flange and same connectors - allowing an easy and straightforward means of up-grading performance, accuracy and reliability.

The 250 frame servo-motors are housed in a smooth extruded 250-mm body, suitable for most general-purpose and hygienic applications and have 300-mm pitch circle diameter fixing holes to meet standard, IEC configurations giving simple and flexible mounting. The 250 frame models in the Unimotor FM range are available from any of the 98 Control Techniques' Drive Centres and distributors in 67 countries across the world.

Digistart - New Flexible Motor Soft Starter Range From Control Techniques

A new soft starter range has been launched by Control Techniques. As the world leader in intelligent drives it is perhaps not surprising that the new, compact Digistart range includes many advanced features. The range comprises of two product families, the ultra compact Digistart CS for induction motors up to 110kW, and the Digistart IS, perhaps the world's most advanced soft starter, for induction motors up to 800kW. "The Digistart products are a competitive addition to our range of drives and will enable our customers to benefit greatly from the Control Techniques' application knowledge of both soft starters in standalone installations and when used in combination with inverter drives" says Product Manager Jeff Ford. The Digistart CS version is amongst the most compact soft starters on the market. It is easy to use, configured in seconds using simple rotary switches, yet provides comprehensive motor protection, so that no external devices are required. It features a Built-In Bypass Contactor that eliminates the need for external bypass contactors and reduces heat dissipation and energy losses by bridging out the power devices once the motor is at full speed. This feature saves panel space and often allows the use of non-ventilated enclosures.

The intelligent Digistart IS version provides industry-leading motor control; with several start methods available including constant current, current ramp and new, advanced "adaptive control". The latter provides an unprecedented level of control over acceleration/deceleration by enabling the user to select the ideal start/stop profile for the application. Adaptive control then monitors the motor performance by analysing each start/stop and adjusting accordingly to maintain optimum control. One application where this is a significant benefit is in pumping where it can be used to eliminate annoying and damaging water hammer effects.

The Digistart IS features a multi-language user interface with in-built start-up wizards for ease of commissioning, real-time performance monitoring and informative event logs. All parameters are viewed in real engineering units and can be displayed numerically or graphically. The user interface is IP65 rated and can be mounted remotely, for example on the cabinet door. Models up to 110kW (220A) feature an internal bypass contactor. Both Digistart CS and Digistart IS support optional network communications with Profibus, DeviceNet and Modbus RTU protocols.
