Hello mostafa; On a MM420 you only have a PI controller for closed-loop regulation. Here is a link to the step-by-step implementation of a PI loop on a Micromaster drive: MICROMASTER 4 (MM4): PI closed-loop control for MM420 and MM440 The analog inputs on Micromaster drives only accept 0-10 V signals. So to connect your thermocouple (Type ?) you will need a TC (specific Type) to 0-10V signal converter; Look at offerings from ABB, for example: Analog signal converters CC range - ABB There are many other manufacturers offering such analog signals converters; for example: http://www.omega.com/pptst/DRF-TC.html https://www.acromag.com/catalog/891/signal-conditioners-converters/temperature-transmitters Your best option is to locate a distributor of such equipment in your neighborhood so you can get support if you need it. Look below for an examople of the type of conversion you should be looking for (from the ABB link above). Hope this helps, Daniel Chartier |
