RE: Using the MAX32630FTHR to read the 1V8 serial output from the Arduino Q debug port

Nice feature. I didn’t realize that the MAX32630 had the capability to set voltages levels. Of course, I don’t have one so can’t try it [emoticon:ca08b2c27c2f40e993e89508acf29e0b]. I’m waiting for the BugHopper to be available.

Thank you for these type of information.

RE: Exploring Automation Possibilities with the ADALM1K Learning Kit

Thanks for the blog, it's interesting to see what you've done with the Python automation (not something I'm very good at).

I'm surprised you're seeing the voltage source values so far from what they're being set to (200mV away isn't 'slight'), and you might want to investigate further what the reason for it is.

This is mine set in turn to 0V, 1.2V, 2.4V, and 3.6V. That's with no load (other than the meter - 10G on the ranges to 2V, and 10M above). The test meter hasn't been calibrated for years, but I don't suppose it's too far out. The results are quite reasonable for what the M1k board is intended to do and the price it sells for.

The most important implementation is to ensure the safety of any humans or animals in the area where the robots operate.

Great! With innovations like the Robot Operating System (ROS) and edge intelligence, mobile robots are becoming integral to the digital transformation of manufacturing, driving smarter, safer, and more connected factory operations.

Its worth a mention the IGBT bridge operates in 4 quadrants - motoring and regeneration. The regen is helpful to EV efficiency in recharging batteries from vehicle momentum. In industrial controls, regen energy can be dissipated in a dynamic brake resistor, or pumped back to the grid using a regenerative converter front end. Real magic happens with a regen front end that eliminates harmonics and is also adjustable power factor correction.

"The disadvantage is that the VSD power supplies are now exposed to all of the voltage transients existing on the factory-wide 24V supply system" ....I've usually seen 24Vdc ( other other control power volts) for the VFDs are fed from a dedicated bulk 24V supply in the DCS system that excludes discrete IO. Discrete IO is fed from local panels, distributed, 24V power supplies. Suppressed 24V small relays coils are OK , once solenoids and big contactor coils get involved, those are fed by another bulk supply that can be tolerant of "dirty" transients.

Interesting approach.

Good discussion on the power management requirements in variable speed drives (VSDs). It highlights very well the importance of managing different power domains, providing appropriate ground referencing, and ensuring isolation to protect against external transients. Thanks for sharing

RE: Getting Plugged In: The AC Input Stage of a Variable Speed Drive

The AC input stage of a Variable Speed Drive (VSD) serves as the primary power path from the AC grid supply to the DC/AC inverter stage and ADI can help with this with it's products and solutions.

Just as a mention, inrush protection is often referred to as the pre-charge circuit.

It is also worthy to mention:

1) EMI filters, input line chokes, SUP (a.k.a. TVSS) , AC input contactor , etc are typically not provided with the inverter, and need to be provided separately.

1) AC input fusing is often external to the drive, not provided with the inverter. This fusing is typically fast acting fuses, semi conductor or C type. Not slow blow for protecting thermally for magnetics.

2) The AC input can be single phased with derated output applied.

3) The DC output of the AC input stage often has access terminal boards to provide application flexibility. PV (solar panels) input , regenerative AC input feed ( power pump back to the AC source ) , dynamic braking ( resistive load on DC for bleeding off regenerative energy from the AC output side ) , and DC bus energy sharing with multiple drives in a process control system.

Nice update.

The primary benefit of using VSDs is energy efficiency. They optimize motor performance, potentially reducing global energy usage by up to 10%. ADI has many offerings to help you with that.

dont forget fans & pumps - a big part of applications

printers, spindles, and other positioning applications get their own volume

winders are in a world of their own
