Trainers as Learning

ACS Motion Control offered a free software suite with advanced motion control capibilities, with full simulation and with advanced analysis tools. Students built four control units with two DC servo motors and four remote units with two DC servo motors.

Students would study topics like tuning, homing, host-follower, camming, position lock on a world class muti-axis controller. The SPiiPlus’s ability to control motion to sub-nanometer tolerances makes it the design engineer’s choice in the semi-conductor or medical industries.

Originally, this unit was built by the Electronics Program. The video game GRID provided the graphics and electrical signals that represented forces the driver would experience real time.

The Automation Program upgraded the drives to a ACS SPiiPlus CM and a C#.NET operator interface. It could also take photo with the driver’s score and post it to Facebook automatically when requested.

A 25 Hp motor donation and a 20 Hp ABB frequency drive led to this trainer design. It featured a wired operator interface box and a lock out switch for motor servicing. 

This advanced process machine featured a few off-the-shelf components mounted on a student designed modular process line. 

A hopper for the bottles picked out a bottle, put it in the right orientation, washed out the bottle, filled it with RO water, screwed on the cap and attached the label.

Product labels are attached to boxes just after the product is boxed. The labeler is suspended over the conveyor system and is adjusted in height to ensure good label transfer as boxes travel under it.

This student designed stand was fully operational featuring accurate and stable height adjustements and secure labeler mounting. Powder coated black as a finish.

This is one of my favorite motion control projects as I used it every day. A company donated a 500-pound force Thompson linear actuator. A student designed the stand. Another linear actuator for tilt. Powder coated black and she’s a beauty – very practicle too!

Two Emerson frequeny drive donations and two trainers. One had a industrial machine base with motor, coupler and a pump installed that could be used for laser alignment training. The other had a slightly imbalenced motor and was used for resonance training. 

We did a lot of projects with the help of the welding program.  When they asked for help upgrading this old sheet metal roller, we took on the project. We added a frequency drive for adjustable speed control which also ramped up the speed slowly making it easier to control the feed. The added footswitch made the roller safer to operate. 

A local manufacturer used hundreds of these Adept pick-and-place robots. We got a donation of four robots with controllers. We made two dual robot carts that could be operated indepenantly or coordinate together passing parts between all four robots.

This teaching location had a lot of lab space, but limited areas for teaching students. This workstation could display videos, power points and demonstrate software actions. It had UPS backup and could be moved to a new location powered on.

It also featured a media computer running Adobe Preimeire Pro that could capture, edit, and render videos projects.

This compact GE 90-30 PLC trainer could do all the PLC lessons with it’s eight inputs and sixteen outputs, but it also served as a troubleshooting trainer. 

It had three air cylinders, solenoids, a relay, a vacuum generator, a strain gauge, a vacuum gauge and an analog input. It simulated a process machine which could be sequenced as a programming exercise or a working sequence could have troulbles inserted.  

This trainer was small to travel well, but featured full motion control learning experiences on both linear and rotary DC servo drives.

Topics like tuning, homing, limits, encoders, and synchronized motion were easily demonstrated on this trainer. A few inputs and outputs gave learning an opportunity for programming motion responses.

The Welding program did a lot of projects for us and here’s where we helped them out. A commercial rotary welding station would have cost north of $5k – this unit less than $600.

It featured a horizontal and vertical rotary stage with speed and direction controls for each. Seperate foot switches started and stopped motion. Both could be used at the same time with proper shielding. 

These eight-axis motion controlers with two-installed drives were selling new on Ebay for less than $500. Adding a remote IO block was easy with CAT5 Ethernet cable. 

These world class controllers could control motion in the sub-nanometer range with extreme accuracy finding many applications in the medial and semi-conductor industries.
