Did You Know? Labeling Drives and Controllers

Our ST5 and ST10, STAC5, STAC6 and STM stepper drives with Q programming are well suited for labeling applications. A product sensor can be tied to one of the digital inputs, triggering a WI (Wait Input) command when the product nears the labeling position. To prevent wrinkling or tearing, the label must be applied at the same speed the product is traveling on the conveyer.

The drive measures the conveyer speed using a “master encoder” whose AB quadrature signals feed into the X1 and X2 inputs. The FE (Follow Encoder) command automatically ratios the label speed to the master encoder frequency, and monitors the label sensor, positioning the label at exactly the right location on the product. The Q programming’s powerful math capability can provide additional customization and control.

Another option for labeling is to use a basic step & direction drive like the STR2, STR4, or STR8. In this approach another controller in the machine, usually a PLC or proprietary controller, provides the control and synchronization with the master encoder, and commands the motion of the stepper system through step (pulse) and direction signals.

Whether you choose a drive with Q programming or a basic step & direction drive, Applied Motion Products offers another major benefit in labeling applications. Our proprietary anti-resonance algorithm provides excellent smoothness and increased useable torque over the entire speed range. When step motors run smoother and with more available torque, it ultimately means faster line speeds and higher throughput on the labeling machine. The anti-resonance capability is available on all Applied Motion stepper drives and integrated steppers.

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.
