Digital servo amplifier


Aerotech has launched a new digital servo amplifier with a linear power stage for ultra-high resolution brushed or brushless linear and rotary motion control systems. The new compact ML series amplifier is intended for lower power use but maintains the very high performance characteristics required for nanometre and microradian level precision positioning applications that are acutely susceptible to electrical noise, and where PWM servo amplifiers become unusable. The DSP based ML range is designed for minimal radiated noise to allow the servo system to provide exceptional levels of speed control and in-position stability for ultra-smooth motion profiles, and to ensure negligible interference levels for sensitive processing and measuring equipment.

Aimed at very high resolution motion systems applications as found in NDT, MEMS, vision systems and microscopy but with less dynamic performance requirements, the new amplifier is available in three versions: as the Ndrive ML option for Aerotech's A3200 software only motion controller; as an entry level version of the Soloist™ ML integrated single-axis position controller range; and as a low-cost linear drive stage solution for the multi axis Ensemble™ ML, a networkable and panel mount motion control system.

The basic specifications for the ML series linear amplifiers in all configurations includes 5A continuous/10A peak current rating with a customer supplied DC bus voltage of +/- 40 V and a control supply requirement of 18-36 VDC. A single 16-bit ±10 V analogue input is used for direct interfacing to the motion controller with an ESTOP sense input included.

The ML features primary and secondary incremental encoder interfaces which are optionally equipped with Aerotech's MXH hardware based multiplied encoder technology for up to 65536 times quadrature output. Using a 1V p-p sinusoidal encoder which does not require a costly power supply, this level of multiplication has a 2MHz analogue input frequency that allows nanometre or microradian level resolution across Aerotech's wide range of high precision direct-drive positioning mechanics, without compromise on top speed.

The MXH encoder option also enables the single axis Position Synchronised Output (PSO) feature to be implemented at the highest level. Aerotech's PSO is a powerful algorithmic software tool that precisely coordinates the real-time position from a linear or rotary encoder with high speed output pulses from the controller which are be used to trigger external events.

This feature is widely used in applications such as laser micromachining or position critical NDT where exacting, no compromise synchronisation is required between laser firing or sensor reading and the axis path position.

For the alternative software based MXU encoder version, the encoder interfaces have a 4096 multiplication factor and both MXU and MXH encoder options include end-of-travel limits and home inputs on the primary feedback encoder. An optional I/O expansion board is also available to equip the ML drive with 8 opto-isolated digital inputs and 8 digital outputs (sinking or sourcing) in addition to single 16-bit analog inputs and outputs, and a brake relay output.

As the ML series linear stage amplifier does not include an integrated power supply and the I/O expansion option may not be required for some applications, the drive can be a low cost solution and additionally its small footprint may be advantageous in space restricted OEM applications.

The ML drive's 10A peak current rating will provide more than sufficient power for the majority of micropositioning applications, however where more useful power may be required and in areas where amplifier temperature rise must be kept to a minimum, a water cooled version is available. This version can provide a 35% increase in usable power.

In addition to the ML range, Aerotech also produce linear stage amplifiers with 2 & 3 axis PSO capabilities, integral mains power supplies and built-in I/O and fieldbus interfaces - offering the superb linearity, high bandwidth, zero crossover distortion and ultra-quiet EMC characteristics of the ML series. These control options and higher power versions are available throughout the A3200, Soloist and Ensemble ranges, and in addition Aerotech offer a full complement of PWM stage amplifiers for very high speed and heavy load precision positioning applications.

All of these Aerotech drive technologies may be freely mixed for multi-axis positioning systems ensuring that each axis is cost and performance optimised. A choice of PC-based software-only, rack or panel mounted motion controls in single or multi-axis formats allow optimal performance with diagnostics and comprehensive features that aim to ensure fast product development and commissioning, reduce positioning errors, improve throughput performance and ensure time-saving and quality improving benefits.

New technology for Hydrogen alarms

Over the last few months Quantitech has supplied DPSS Cabling Services with unique hydrogen specific gas monitors for use at 14 different back up power facilities that utilise uninterruptible power supply (UPS) systems.

UPS equipment is often preferred to diesel generators because it not only provides surge protection, but also eliminates the use of fossil fuels and any associated exhaust related issues. However, lead acid based battery systems have the potential to emit hydrogen if there is any damage or leakage. Hydrogen is a highly dangerous flammable gas, so DPSS has installed the new gas detection technology capable of detecting low levels of hydrogen, even in mixtures of other gases.

DPSS ordered the HY-ALERTA™ 600 version of the hydrogen monitoring technology, which provides hydrogen-specific leak detection and measurement of hydrogen concentrations as low as 4000 ppm and can be scaled to any concentration up to 5% hydrogen by volume. The monitor is designed for either ceiling or wall mount and has no cross sensitivity to other combustible gases, thereby eliminating false positive alarms and ensuring safety system reliability.

DPSS's Jeff Redhead commented, "As specialists in the field of the design, survey and installation of cabling and associated route works, we often provide the support works for UPS systems. This equipment is becoming more common in applications stretching from shopping centres to military installations, so we are delighted that a reliable hydrogen specific technology is available to monitor at the LEL (Lower Explosive Limit) and provide an alarm in the extremely unlikely event of a leak."

The hydrogen detection technology was developed by H2scan, a US based company represented in Britain by Quantitech. Keith Golding is Managing Director at Quantitech. He says. "There are many applications for which hydrogen specific monitoring is important. These cover both health and safety, and process control within a wide variety of industrial applications including petrochemical refineries, hydrogen production, chlorine manufacture, nuclear power/waste, fossil fuel power, chrome plating, research, semiconductor and electronics manufacture, abatement exhausts, transformer oil, fuel cell technologies and of course lead acid battery monitoring."

Power station has Triple-Redundant Mark™ VIe DCS on nuclear turbine generator

NextEra Energy Seabrook Station is just 50 miles north of Boston (MA US) on the New Hampshire coast. The total plant output is 31,200 megawatt-hours per day.


Benefits of the Mark™ VIe TMR digital control:
• Reduced maintenance, costs, and downtime
• Increased mean time between failures (MTBF)
• Modern maintenance tools and diagnostics for troubleshooting in real-time
GE Energy has been a partner with the Seabrook Station since 1987. Most recently, the plant upgraded its turbine control system to the Mark™ VIe Triple Modular Redundant (TMR).This modification makes the turbine generator more reliable and easier to maintain, reducing the number of forced outages and power reductions.

The end result of this upgrade is that it makes existing power generation and delivery systems more reliable, thereby reducing the overall cost to produce power.

GE Energy supplied all control equipment, engineering, drawings, technical direction, start-up, and commissioning for the new turbine control system. The scope also included a simulation trainer for the equipment supplied, on-site training, and spare parts.

The new Mark VIe TMR digital control system replaced the old analog system and provides a road map for maintainability into the future. The Mark VIe TMR eliminates single points of failure with mechanical devices in the Front and Mid Standards by modifying speed picks, trip interface, and thrust. The upgrade includes trip reduction software, which eliminates the need for online overspeed testing. System redundancies also further eliminate single points of vulnerability and reduce downtime.

Gas over oil pipeline actuator

The Shafer SH Series is designed for high reliability with a long service life and is ideally suited to critical applications

Emerson Process Management's Shafer™ SH Series of gas-over-oil valve actuators are ideally suited to automate valves used for gas transmission as well as at compressor stations, gathering plants, storage facilities, meter runs and many other applications. Designed for fifty years of operation, the actuator has a 15 year seal life and a ten year, industry-leading warranty.

The SH series actuator is operated by hydraulic oil, pressurised by the pipeline gas. Powering the actuator with oil prevents the internal corrosion associated with other actuator designs. The actuator is designed so that the gas is contained within two tanks, half filled with hydraulic oil. Contaminants and moisture in the gas settle to the bottom of the tank where they can be easily drained.

The actuators can be used for standard on/off service or as part of an Emergency Shutdown System (ESD). Three sizes of SH are available to suit DN 50 to 200 (2” to 8”) valves with a torque range between 254 Nm and 2034 Nm. Torque is evenly applied across the whole range of movement, making the SH Series ideal for plug and blowdown valves. The compact actuator package is operated by solenoid valves which are factory piped, ready for operation. A switch box provides open/closed feedback to the operator.

The helical spline technology contained within the actuator does not cause stem side loading, which other designs can be prone to do. Stem side loading can cause premature packing or seal wear and leakage. The SH series is powered by pipeline gas in the pressure range of 27.5 bar to 103 bar. It is also possible to operate the actuator manually when required, for example during commissioning or in situations where pipeline pressure is not available.

Maintenance requirements are minimal; the drain valve in the tanks needs to be opened periodically to remove the contaminants and water that have settled out of the gas. This should normally only be necessary once a year.

PSU has digital remote control

The new CPX400DP is the latest in the CPX series of PowerFlex regulated power-supply units from TTi, and is the first to incorporate digital remote control interfaces.

Based around the power electronics of the widely adopted CPX400A unit, the new supply incorporates important new manual control features in addition to the digital interfaces. These include settings lock, isolated voltage tracking, and synchronous switching of the two outputs.

To achieve maximum flexibility for remote control applications, RS-232, USB, GPIB and LAN (Ethernet) interfaces are all provided as standard. The LAN interface is compliant with LXI (LAN eXtensions for Instrumentation).

The TTi PowerFlex design offers a constant-power capability allowing higher output current at lower output voltages. Each output can provide 60 V at a maximum current of 7 A. As the voltage setting is reduced the output current capability increases up to a maximum of 20 A.

The CPX400DP is a dual-output supply with two completely independent and isolated outputs, each with a 420 W capability. The outputs operate in constant-voltage or constant-current mode with automatic crossover and mode indication. Isolated voltage tracking allows easy control for either series or parallel wiring, enabling up to 120 V or 40 A to be produced.

The power supply uses true analogue controls, but incorporates an S-lock function which transfers control of voltage and current from the analogue controls to internal digital circuitry for stability and safety.

Each output has its own on/off switch, but an additional synchronous on/off switch can be used to ensure that both outputs are operated together, an important function for circuitry that can be damaged if one voltage rail is present without the other.

The CPX400DP is housed in a compact and robust steel case which is half-rack width and takes up very little bench space. It measures 210 × 130 × 350 mm and weighs 7 kg. A rack kit is available that can mount one or two units.
