Dynapar ACURO absolute encoders

acruo-2

The Danaher Industrial Controls Group (DICG) announced an expansion of its Dynapar ACURO series of absolute encoders with two new models that incorporate the company’s new opto-ASIC technology platform. ACURO is already a market leader in several key performance metrics, such as communication compatibility, networking speed, high resolution, and lowest current draw, among others.

The application / function are as follows:
The new opto-ASIC platform extended throughout the ACURO line now provides advantages that make absolute encoder technology applicable to a wider range of motion control and servomotor feedback applications. The new ACURO 36 and ACURO 110 models extend the ACURO series to applications in the small motor, packaging and textile machinery, and medical equipment sectors.

Absolute encoders improve machine reliability because, unlike incremental encoders, they always know their position, even at startup or after a power failure. DICG technology and manufacturing breakthroughs have reduced the cost of absolute encoders, so that they are now finding acceptance in every kind of application, not just the high end, demanding few.

Broader range of sizes – Only 36mm in diameter, the new hollowshaft ACURO 36 encoder is more than a third smaller than previous models in the ACURO line. At 110mm, the new hollowshaft ACURO 110 encoder accepts shaft sizes up to 50mm. Both are available in motor drive or standard industrial versions.

Low-profile gears shrink size, increase reliability – The ACURO 36 is one of the few encoders that use a gearbox instead of a battery to provide multiturn resolution. The low-profile mechanical gearbox allows a lower installation height than battery-buffered counter solutions.

Thin as a dime, the gear set facilitates an installation depth of just 31 mm – one of the shortest in the industry. Small encoders are especially important to motor OEMs, who are under pressure to continually shrink their designs.

In addition, the gears eliminate dead batteries as a potential source of downtime, and eliminate the need for battery maintenance. Running at speeds up to 12,000 rpm, the gear set is nonmagnetic and immune to interference in such applications as welding or motors equipped with powerful brakes.

New OPTO-ASIC generation platform:
The ACURO 36 and ACURO 110 encoders are based on DICG’s new generation platform based on opto-ASIC electronics, into which multiple functions are highly integrated. ACURO was engineered for field dependability, re-designed from the predecessor’s 150 parts and five circuit boards to less than 30 parts and just one board. Reliability is enhanced by minimizing the number of printed circuit boards and soldered connections. The new electronics also enabled Danaher designers to increase the temperature specs on the motor drive version to an industry-leading 120 degrees C – ideal for today’s smaller, hotter running motors.

The ACURO Series has the lowest current draw of any absolute encoder, at just 45mA for the single-turn version and 85mA for the multiturn version.

The new platform is consistent across DICG’s manufacturing plants worldwide. Globally based companies are assured of receiving the same design encoder no matter which region it was manufactured in. This allows company managers to reduce costs through component standardization.

The most communications protocols -The ACURO Series encoders can communicate with any type of control system using common formats, ranging from parallel to such field buses as profibus, DeviceNet, CANopen, CAN Layer2 Interbus, and SSI.A 2048-step sine/cosine signal (1Vpp) is also available for dynamic control. No other encoder offers as many communication options.

Network speeds five times faster:
The ACURO Series was the first to use the new BiSS (Bidirectional Synchronous Serial Interface) protocol. This freely licensable, open-standard protocol supports networking speeds five times faster than proprietary encoder protocols. Using the BiSS protocol, engineers free themselves from restrictive, proprietary bus standards, and achieve data throughput up to 10Mbaud using standard drivers and cables longer than 50m.

As BiSS is all digital, it eliminates the added cost of A/D converters needed in drive systems that connect to encoders using proprietary protocols. BiSS is hardware-compatible with the SSI protocol, simplifying integration.

Differentiate features are:
High accuracy:
The ACURO 36 offers up to 12-bit multiturn and 22-bit single turn resolution – one of the highest accuracy encoders on the market. The ACURO 110 offers 17-bit single turn resolution. High resolution allows precise control of machine motion and increases machine reliability.

More diagnostics than any other encoders:
The new ACURO Series offers more built-in diagnostics and alarms to monitor current and temperature than any other encoder. Optical sensors internally monitor the amplitude of the encoder signals, and exceeding the limit values will result in warning messages. A single-step code check ensures that the encoder signal reflects the recorded turn, bit by bit. The internal signal processing function checks each individual increment for possible occurrence after the previous event. Any violation of this rule, possibly due to disk breakage or mechanical overload, will lead to an alarm.

In addition, a self-monitoring feature checks the operating hours and signals a warning message to initiate preventive maintenance. What’s more, the BiSS protocol can report operation information that can be used diagnostically, such as torque, temperature, and acceleration.

Large Solid-Core Design Makes Monitoring Larger Circuits Easy

Ground Fault Detection at Docks and for Other Large Equipment Using High Current Circuits

Since the early 1980’s, NK Technologies has been designing and manufacturing ground fault sensors for industrial and commercial applications. These applications include protecting heat trace and snow melt cable, submersible pumps, water features, pools and many electrical heating applications.

In the early 2000’s, NK Technologies’ engineers designed a larger sensor with the capacity to monitor circuits up to around 300 amps. For applications drawing more current or using conductors that are larger than would fit through the sensing window, an external “zero sequence” current transformer was needed; the fault would be expressed at 10% of the actual fault current. To increase the amount of current through the sensor, the CT secondary is looped two or three times through the sensing aperture to get the current up to a detectable level. This approach is not very attractive, even to those who frequently install electrical equipment in less than ideal conditions. Now the design engineers at NK have developed a sensor with an aperture measuring four inches in diameter. This allows conductors carrying 800 amps or more to pass through easily.

The National Electric Code 2011 added section 555.3 to require ground
fault circuit protection for all circuits feeding a dock. The trip point was
specified to be 100 mA. The 2017 Edition reduced that trip point to 30 mA.
Not all jurisdictions have accepted this lower detection level, but they may
in the future. The smaller NK Technologies’ sensors can be used to monitor
individual circuits to each slip at a dock, with the sensor output energizing a shunt trip breaker operating mechanism circuit. The entire feed can be used to monitor the main feeding circuit to the pedestals, to again complete the circuit to operate a shunt trip breaker.

Docks and marinas are not the only place where higher current circuits should be protected with ground fault detection sensors. Adding ground fault protection to amusement park rides, whether permanently installed or temporary, should be considered even in places where it is not specifically required under NEC section 525 or 518. The last thing anyone would want is to be shocked while taking the newest roller coaster at their favorite park.

Another place where there is a need for larger ground fault sensors is on chair lifts at ski resorts. The motors and lighting required by this equipment draw considerable amounts of power and there is always a chance of dangerous conditions when the environment is wet and the skier’s clothing is soaked. Whether controlling a contactor or a shunt trip breaker, ground fault sensors from NK Technologies are the first choice by experienced personnel and designers.

AG-LC Ground Fault Sensors for Monitoring

Higher Current Circuits

AG-LC series ground fault sensors are the latest design innovation from NK Technologies. The NEC added section 555.3 to require ground fault protection of the main over current device feeding marinas and boat yards. These services are often carrying up to 800 amps; most sensor designs will not allow the conductors to pass through a single sensing ring.

By designing a sensor in a large solid-core housing, the conductors will not have to be passed through a separate sensing device like a zero sequence current transformer. This design makes monitoring of larger circuits a breeze, whether to protect boaters, or large equipment like amusement park rides or gantry cranes.
