Bonitron offers different product to support your Ac Drive applications that require braking like, hoist , descending conveyors, escalators and other similar applications. The industry generally uses transistors and braking resistance, but this solution gets your energy converted to heat. This has two effects, the loss of energy and the increased need for air conditioning. The other option is to use a regeneration module that will re-inject energy onto the plant grid. This module is compatible with all drive that has a connection on their DC buses.

Do you have critical applications that can’t be interrupted or voltage variations that cause your drive to trip ? For example, the time it takes for the generator to switch from the Hydro voltage to the generator may be long enough to trigger a fault on your drive or your plant is at the end of the line and the voltage fluctuates and trip the drive.Bonitron is a name to remember in those situation they manufactures multiple solution. They have units called UPD. Like a Ups these units take over during power outage but provide only DC energy. The AC Drive have already a power converter so it is not necessary and much more efficient to not do the conversion 2 time . The result is a more reliable and more price effective solution than a UPS. Also as the solution is parallel it does not prevent your Drive from working if the UPS has issue.
If your voltage interruptions are short. There is also a solution based on capacitors that will be plugged in parallel to the DC Bus of your Drive. This additional capacity allows energy to be stored to overcome the problems of voltage variation.
Your Drive can also trip on over voltage, which is normally due to regeneration of your motor when it is being tracked by the load. The generator effect of your motor inflates your DC bus and the drive trip to protect itself. It is then necessary to precede to deflate the DC bus by consuming the excess energy. Option 1, use resistance to burn energy or Option 2 returns this surplus on the power line. The greener solution is regeneration, because the energy is not wasted in heat but rather returned so that other load can consume it. There are accessories on the market to create a common DC Bus with multiple drive , this way an accelerating drive can consume the current of another drive in deceleration. This common bus solution will reduce the size of the regeneration unit in addition to limited to one unit per group of drive . The beauty of the solution , it can be done with regular of the shelf drive , all you need is a connection to the DC bus of the drive.
Another interesting option is for cycle loads, which go from motor to generator state constantly. Like an oil pump jack. When the pump goes up it consumes power when it comes down it regenerates. Capacitors can then be installed to store during the descent and provide energy to the climb.
Tr Electronic known for their programmable coders now offers a programmable absolute encoder approved for functional safety SIL 3 PL e. Available on different bus it integrates with different controllers to give you fonctional safety . Unlike conventional encoder the features are implemented in the encoder. For example, the safe speed monitoring or the safe position monitoring is available directly in the encoder. The programming is done in the software of the client controller using a profile downloaded in this one. Available on different network (Profinet, Profibus, Ethercat, Open Safety, Powerlink) are easy to integrate .
Very interesting for the entertainment industry, where man and machine must have to cohabited

Stober now offers a solution to meet the ISO 13849 standard for machine safety. By combining a brake with a Stober gear assembly and a brake on your servo motor Stober you get a mechanical redundancy. In Europe Stober offers the whole supervised by a safety controller integrated with the Servo Drive . In North America the solution is integrated with the Rockwell security controllers and Servo Drive
Why STOBER? With over 80 years in gearing experience and over 30 years in motors, STOBER has the knowledge and expertise to create the best gearboxes and motors in the industry.
Servo solutions range from planetary gearheads to helical bevel gearboxes to hollow bore motors to rack and pinion solutions. This diverse offering means we have a solution that will meet your needs. Our compact helical bevel reducers allow you to use your current machine setup. If you need a completely engineering system, let our product support team help you size your gearbox.
Our gear reducers for NEMA motors are ready to handle tough environments. An average mean time to failure of 8 years and a standard 3 year warranty means you can trust a STOBER gearbox to stand up in harsh conditions. STOBER gearboxes are lubed for life and don’t leak oil. No maintenance. No downtime. Not only will you save money on downtime and maintenance, our gearboxes are up to 97% efficient, therefore reducing your energy costs.
Why not looking at the micro Speed Elovis sensor (non-contact speed and length measurement)
A new contactless technology is available to replace the technology with encoder and wheel in contact with the material. Laser-based technology is capable of measuring speed and displacement, thereby eliminating the slippage and maintenance problems associated with wheel systems. In addition to the much greater accuracy of this technology allows to self-finance its investment. The system with an error of only. 05% VS 2% for coded wheel systems allows you to save thousands of dollars annually in material and customer complaint.
Bonitron have a new approach to dealing with undervoltage problems with AC drive. They have developed a system that plugs into the DC BUS and uses super capacitors or a battery bank to store the energy needed to ignore voltage variation or power interruption that cause the drives under voltage trip.
The system can support full voltage losses of a few cycles to 15 minutes without loss of torque, time to finish your precious pieces, without breaking tools, park the head of the machine and simply continue to Produce.
Bonitron’s UPD system is a solution to increase your productivity and decrease downtime
