MP-3800 Compact Switchmode Lab Power Supply 0 - 24V
Current output: 6A continuous at 24VDC
My questions/research:
I have read that it is recommended to use an un-regulated power supply and that switch-mode regulated supplies can often fold voltage to protect itself as it can see the instantaneous current as a short
True or False? Should I be concerned?
The highest RMS current setting on the DM556T is 4.0A (Peak 5.6). With normal DC motors I wouldn't generally worry, but as steppers operate a little differently I'm not certain how much of an impact 0.2A will have - I assume it'll just be a hit to torque and nothing else?
If my motor needs 4.2A/phase, we can multiply that by 1.4 to get the "general" load of 5.88 (lets say 6A)
Am I pushing it with my 24V, 6A supply at this stage?
Hi @TomGeorge, yes, apolgies I have updated the original post. I'm a software engineer, have previously worked in industrial settings ie with PLCs, ok with basic RLC circuits, first time playing with micro controllers.
PLEASE don't update old posts, it disrupts the flow of the thread and makes it confusing to anyone who reads this to help with a problem they have.
Your update, still will not compile.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.
Thanks but Fritzy images are not comprehensive enough.
'not used' is not true - you assigned an interrupt to it. How did you wire that pin? if it is left open it can receive interference and it may trigger your interrupt.
