PWM Driver 5A
Has anyone had any experience whereby they have used a single IQAN PWM out with a 5A load ? The data sheets say "no" but I am just wondering if this is possible if the number of outputs used simultaneously, is controlled.
XA2 Temperature Warning Threshold
Was wondering what the temperature threshold is on XA2 units before the internal temp will trigger a warning in the system?
Supported Radio controls
Does anyone have experience to use proportional radio controls via ICP/J1939/CANOPEN. I'm interested about vendors which have radios which i can use in my project.
I found that Magnetek radios have ICP protocol available but is there any other vendors.
How IQAN XR radio module is used? Can it communicate directly to some handheld radio or with receiver?
MC41 PWM out HS+LS flyback diode wiring question
I have a MC41 setup where I need to use a bidirectionnal CAM output in PWM mode to drive a bidirectional valve (2 coils). There is a mention to not use a flyback diode in closed loop control but is it ok to add diodes on coils if the outputs are used in PWM mode, not in current output? I tried it and it seems to work just fine.
I want to add diodes as there will be an emergency operation switch installed to directly power the coils. We want the diodes to prevent high voltage spikes to the MC41 module and the switches.
Found on the forum:
With IQAN-MC3 and IQAN-MC43, -MC42 and -MC41, the internal clamping diode is not disconnected when COUT pins are used as open control PWM.
Does that mean that we do not need to add diodes?
Open Load Error when MD4 Output turns off
I am trying to control a relay with an MD4 output (relay turns on a light when certain conditions are met).
When the IDC channel that controls the DOUT channel goes to false (output turns off) the MD4 is displaying an OPEN LOAD error.
We are running IQAN Design 4.07 on this unit.
Any recommendations?
MD4 real time clock and internal temperature sensor issue
Hi,
I have several issue comes from a customer who run MD4/MC31 multimaster system.
They have MD4 who are not anymore able to keep the RTC.
To be sure, I took a kit apart and tested it myself. Finally, I move the MD4 alone and tried it with a very small program. Only value to show date/time/temp.
When it boot, the RTC is resetted and the temperature is OK (around 40 Celsius).
But when I update the date/time from iQanRun, the date and time appear to be OK, but the internal temp goes to -1C and give critical error.
I did a short video to show what I did and to show what's append.
Thanks!
There is some picture to complete:
Looking for vehicle schematic example with display, controllers, joysticks and etc.
Need a good example of vehicle electrical schematic with Parker controls.
IQAN-LM 3D Models
I am just using up a couple of Legacy LM - 30 Joysticks that we have in stock and I could do with a 3D model for it - I was just wondering if anyone has one?
multiple camera input
Hi all
I have a new application requiring multiple SV cameras feeding into a MD4 master. I only need to view one or two inputs at any given time, but all four camera feeds need to be available and switchable at any time. I know i will have to use some form of ethernet switch for the multiple feeds into the C4 port of the MD4, but don't know if this needs to be a managed or un-managed switch? Has anyone out there done this sort of thing with the SV cameras, and if so can you help with the app file in the MD4 and recommend a suitable switch?
many thanks
A
Hello.
We have done some testing with rugged ethernet switches to see if they work with the MD4 and SV cameras.
They are unmanaged switches so you only connect them and are ready to go.
These two switches were tested with three cameras (only had 3 to test with) and was found to work.
Molex DRL-750Murr
Electronik Art.-No. 58160
Test were also done on 'Moxa TN-5305' and 'Phoenix Contact FL switch 1605 M12'.
These two switches experienced problems when more than one camera were added.
