I have worked with this type controller extensively before and I have the following comments on the above statements.
1. The voltage reduction of a Nola type controller will work on a large number of escalator applications. Jraefs comment that the escalators need to be minimally loaded is...
Thanks for the input guys. I think I may not have been clear in my initial desciption. The system is designed to control the motor to optimize power savings. What I am looking to do is provide a way that if a fault in our control circuitry exists, the load will still be powered, it will just no...
I am building a DSP driven motor controller and I am looking for a way to implement fail on functionality. Currently the DSP controls a triac that turns on and off when needed. Unfortunately, it is driven by the on board power supply and in the event of a controller or power supply failure I...
