Motion Control

High-Torque Drives

Schneider Electric Motion USA (Marlborough, CT) offers Lexium MDrive NEMA size 23 drives with high-torque stepper motors as an alternative to standard motors. Closed loop performance of the drives eliminates possible motor stalling, and delivers continuous torque at low speeds. It eliminates tuning, and reduces heat and energy usage with variable current control. Various industry-standard communication protocols are available, including EtherNet/IP, ModbusTCP, Profinet, CANopen, and serial RS-422/485 with programmable motion control and pulse/direction input.

Actuator Control

The DCH Series actuator control from American Control Electronics (South Beloit, IL) combines an AC-to-DC switching power supply with a regenerative PWM drive to create an all-in-one solution. The control is suited for applications requiring control of 12 or 24 VDC motors when only 115 or 230 VAC power is available. With an isolated front end, this series is compatible with a 0-5 or 0-10 VDC analog from any PLC. With an 8-bit onboard microprocessor, the control can be customized in many applications to replace a PLC. The series also provides an alternative to using higher-voltage controls with the output voltage turned down, which results in current spikes. The control includes an industry-standard microprocessor used on popular PLCs. A modified option allows for linear positioning control of actuators to within 1/1000 of commanded stroke length with the use of feedback resistors. Standard variations include options for torque, cycling, or positioning control. Standard I/O is 1 analog and 4 digital, with custom configurations available.

Motor Controllers

PITTMAN® Motors, a business unit of AMETEK Precision Motion Control (Harleysville, PA), announced IDEATM PBL4850E programmable 3-phase brushless motor controllers that let users create distributed standalone motion profiles without the need for additional motion control components such as programmable logic controllers or field communication buses. The controllers feature automatic population of motion profile parameters based on the entry of a few motor characteristics. The 4-quadrant brushless controllers utilize sinusoidal commutation. They incorporate two motion profiles: trapezoidal and s-curve.

Magnetic Encoder

The Model 30M low-profile, 30-mm-diameter magnetic encoder module from Encoder Products (Sagle, ID) provides incremental feedback by means of advanced sensing and signal processing technology. It combines a Hall-effect sensor, signal processing circuitry, and a small magnetic target that can be affixed to a rotating shaft via an optional shaft adaptor or insert. With a wide sensor-to-magnet air gap, the encoder tolerates shaft misalignment. The encoder offers resolution up to 1,024 CPR, a maximum frequency of 350 MHz, up to 8-pole commutation, an optional index channel, two voltage selections, and four output types. Connector options include an 8-pin M12, or an 8-pin or 16-pin Molex with an integral strain relief. For Free Info Visit http://info.hotims.com/61058-305
