Motor drives "hunt" for success

MalAsia strikes drive manufacturers, but motion control is stepping up, according to CONTROL Senior Technical Editor Rich Merritt's Product Roundup of motor drives and motion control devices.

The control panel/keypad on the ACS550 low-voltage AC drive resembles a cellphone, from the way screens pop up to the Help key. It has separate Start and Stop keys; parameter set keys that use arrows for incremental up or down sets; and two soft keys, the functions of which change according to the operating state of the panel. A built-in Help button, start-up assistant, maintenance triggers, diagnostic assistant and a real-time clock assist in operator setup and use. ABB

Miniature Drive Steps into Action
The Integral E integrated drive and stepper motor is a plug-and-play solution that reduces component count and cabling and decreases product integration time. Several drives can be combined with a single ACR1505 motion controller to form a complete multi-axis motion control system for use in microarrayers or liquid handlers.

Sensorless Drives Tune Themselves
|The Durapulse series of sensorless vector AC drives are available in 1–100 hp models. They have autotuning, 150% starting torque, 150% rated current for one minute, automatic torque and slip compensation, internal dynamic braking circuit, and programmable jog speed. The drives come with 0–10 V, -10–+10 VDC or 4–20 mA analog outputs, 16 preset speeds, 11 programmable digital inputs, four programmable outputs and one analog output. Prices range from $289 to $3,999. Automation Direct

Soft Starter Limits Stress
The Telemecanique Altistart 01 Soft Start provides smooth motor starting control for applications that do not require high starting torque. Soft starting limits the stress on the mechanical parts of a machine and reduces the cost of maintenance and downtime. The starter works with 110–575-V, single-phase and three-phase asynchronous motors, with ratings of 1/4–75 hp, and 20– 60-hp three-phase motors rated 32–85 A at 208, 230, 460 and 575 V. Schneider Electric

Variable-Speed AC Drives
Allen-Bradley PowerFlex 700H and 700S AC drives are available in power ratings from 0.5–450 hp at 400 and 480 V. Machine builders can integrate drives into a manufacturing process using NetLinx, DeviceNet, ControlNet or EtherNet/IP networks. Software includes DriveExecutive and DriveTools SP for programming, configuration, monitoring and troubleshooting. Options include 24-V or 115-V digital I/O plus analog I/O. All drives are CSA/cUL Certified, UL Listed, and CE marked. Rockwell Automation

Motion Controller Uses Fire Wire
Automation 3200 NMotion SMC controller offers 32 axes of synchronized motion control through one interface, expandable to 62 axes. It uses a distributed control architecture that enables it to maintain performance independent of the number of axes being controlled. This avoids the processing bottleneck caused by its previous single-processor control architectures. Trajectory generation is done on the PC, which sends incremental position commands to a drive via the IEEE-1394 (FireWire) serial bus. Aerotech

Seven-Axis Motion Controller
The NextMove ESB provides seven axes of motion control, including up to three axes of servo and four axes of steppers, or seven precision servos. It supports servo loop closure times of 100 µsec and will provide pulse and direction for steppers up to 500 kHz. On board I/O includes 20 digital inputs, 11 digital outputs, two 12-bit differential analog inputs and a precision 12-bit output. Baldor Electric

Amplifier Board Mounts To Motion Controller

The AMP-20540 servo amplifier board attaches directly to the 96-pin DIN connector of the company’s DMC-2143 controller without the need for any cable or wiring. The board drives brush and brushless motors up to 500W. The 6.92 x 4.85 in. board contains four transconductance PWM amplifiers, each capable of producing up to 500 W. It accepts 18-60 VDC, produces 7 A of continuous current, and has a PWM switching frequency of 60 kHz. Prices start at $495 in 100s. Galil Motion Control 

Smart Servo Drive Goes Camming
Compact Compax3 provides position, speed, or torque control, label registration and advanced gearing. Multiple units can be synchronized for multi-axis applications. Units incorporate motor drive, full-feature controller and power supply in a single module. Setup is made easy with an intuitive interface, wizards, online help and an oscilloscope function. Motion controls includes advanced camming, curve linkage virtual master, feed-forward, observer and over sampling functions. Options include analog or step-and-direction signal inputs. Compumotor
