Tolomatic Introduces ACS Stepper Drive/Controller

Tolomatic's new stepper drive/controller, designed for use with electric actuators, simplifies linear motion by automatically configuring all performance data about the actuator and motor. The new actuator control solution (ACS) is a low-cost stepper drive and controller that features built-in configurations for the ERD, the company's low-cost rod-style electric actuator. According to Tolomatic, linear motion is quickly and easily created in the desired linear units (millimetres or inches).

Originally designed as a low-cost replacement for pneumatic cylinders, the ERD range of actuators is now suitable for applications such as product changeovers, pick-and-place, sorting and diverting and heat-staking tasks. Aaron Dietrich, electric products manager at Tolomatic, said: 'The primary goal in designing the ACS stepper drive/controller for the ERD product range was to create a low-cost, extremely easy-to-use drive and control product intended for single-axis actuator solutions.

'What makes creating motion so easy is that, through two simple configuration steps, the ACS drive knows everything about the axis of motion. 'Combined with any of Tolomatic's electric actuator products, the entire axis of motion is available from one supplier,' he added. The ACS is capable of four, eight or 16 move-command modes (absolute, incremental or jog) for infinite position capability. This array of command modes is flexible enough for a variety of single-axis actuator solutions. It also has adjustable motion profile parameters (position, velocity, acceleration/deceleration and force) that are independently configurable for each move.

For energy savings, the ACD has the ability to reduce holding current when not in motion. The ACS is capable of zone output based on the actuator position and it has a force-limiting capacity. The digital I/O is configurable in either 24VDC opto-isolated, NPN or PNP, and the drive/controller is compatible with most brands of 24VDC stepper motors. The ACS comes complete with a starter kit that includes the configuration software and two setup manuals.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
