Re: Global emergency stop via interrupt

Hi Monie How It works. Limit Switches are installed at the Extents of travel East & West If the end of travel is reached then a signal is sent to the MAIC and stops the motor circuit from working. the MAIC can signal east or west travel - but this is interlocked so both cannot happen together Th...

Re: Global emergency stop via interrupt

Hi Monie

That unit is a micro switch not an inductive sensor

Terminals 1 & 2 open when the plunger is operated
Terminals 3 & 4 close when the plunger is operated

Re: Global emergency stop via interrupt

Hi Monie, Monie Emergency stop function Emergency stop should stop contact with SolarTracker. In principle, it is on / off by contact. In case of contact with Emergency stop, LED I7 turns on And here miac RelayOFF (1) and miac RelayOFF (2) must be OFF. When driving away from Emergency Stop, Miac Rel...

Re: Global emergency stop via interrupt

Hi Monie, Monie I use the inductive sensor to stop a solar-tracker in east end and west end. But want a final stop when the solo rack reaches one of the ends. The function here must be a global stop and a final stop on the solar-tracker. I would like to welcome you with a suggestion. so this is a en...

Re: Global emergency stop via interrupt

Hi Monie,

I can do you a drawing tomorrow as ETS Driver has said the machine cannot restart when the stop is released.
You will have to do a "reset"

What is the inductive sensor used for ?

can you supply a drawing ?

Hi Monie I do not wish to dampen your project - but you cannot use software to control Emergency stop functions. They have to be "Hard Wired" You can used the Push button to disconnect the power to the relay outputs then a secondary contact to let the MAIC know that the push button has bee...

Re: Supply pins decoupling

Cheers Jac

thought so frequency .... nice to have it confirmed. Never had a issue with the MKS2's but I wont temp fate with this project but then again never had one ticking at 32 MHz before usually a lot less than this.

Hi You can measure the current with a muiltimeter but It all depends what accuracy are you looking for? Some muiltermeters have uA range but the burden voltage of the meter is high this affects the accuracy of your reading. You can solve this easily using an external circuit. All you need is a resis...
