Hi! Im trying to figure ut a dilemma on a Mg module.... 
Problem is that a servomotor controlled by Vref and position sensor (3 cables) 
Starts to pull backwards as soon as you turn it on, its suposed to fint its own 0-position 
Just found 2 wires (vref + and -) short-circuited on another component....or atleast they where badly damaged. 

Question! Does the MG protect the vref from a short....and how long woud it theoretically whithstand this? 
And and is there any one knowing how to meassure this if my Mg has any broken component? thanks// Kim

Hej! jag försöker reda ut en rejäl huvudvärk med en MG modul.  
denna styr bla. en servomotor som får fnatt och börjar dra baklänges helt plötsligt. den skall egentligen hitta en nollpunkt och stanna där men strömsätter man den så är det något som ger signal att den ska dra konstant baklänges. 

Hittade idag ett par kablar som troligen kortslutits ( Vref  plus och minus ) fast till en annan sensor som övervakar hydraultryck. Kan en kortslutning orsaka haveri i Mg´n ? Eller har den kortslutnings skydd i sig ( isåfall hur länge klarar den en kortis ? )   

Samt hur mäter jag om Vref är trasig? Eller har vi någon här som är kunnigare än en lekman på att mäta upp en Mg lite snabbt?  Mvh// Kim

I am purchased a new IQAN MDL-2 and Trying to get a clone from an older one and install it on the new one . The only connection that i have is a USB but its not connecting at all with IQANrun , tried 3 different cables and its still always showing that its USB(Offline). any help in this matter ?

The view angle of the MD4-5 with part number 20085164 is a -70” till 70” view angle.

But in the upper angle about 25”-60”  the display is not clear or readable. We have mounted the display vertically, and because of different heights the option flip is for us not a solution. 

When we sent an application to the display the blue screen is clear, no read problems, how is this possible.

We are really dissappointed about the touch screen changes of the MD4-5 between the 20085164 and the older 200777773

Kind regards,

Laura

What is the correct installation process for this? This is new to me so i have limited experience. Customer has a damaged MD4-7 and we have a MD4-5 to replace it. Will i be required to run the IQAN software for the install procedure or will i be able to configure what i need on the the screen? Thanks in advance.

Hello,

we got some issue with a MD4 display where the clock reset all the time, we think that it could be some faulty components inside.

have you heard about similar issue

MD4-5 M19 version, having issues with the touch panel. Noticed that the problem is more pronounced when using smaller buttons on screen. By using larger touch buttons the issue seems to be improved but not perfect. The screen responds to the press (it goes orange) but does not actually process the command to exit the screen. Seems very temperamental. Is there a built in delay to prevent button bounce that could be causing this phenomenon? We also tried without the screen protector and had similar issues. I tried without filming and was pressing the screen very firmly and around 6 times before it would register the button press (sometimes it went orange and did nothing, other times it did not even change colour).

Hi All,

We have a motor that requires a PWM negative signal. Using an MC42, anyone ever done this? if so, how?

i need help with choosing a controller to operate at abut 2000 hz for motor control. i currently have a MC43 and it doesnt seem to have the speed required for what i am doing. i get about 100hz

Could someone recommend something?

Hello all, 

I am trying to do speed control of a BLDC motor with a Parker MD4. I have a quadrature encoder for the motor and would like to know how to calculate the speed for the motor using the IQAN Design software. I can calculate the position of the motor from the sensor, but to estimate the speed in rpm, I need to perform differentiation of the position data. I wanted to know if there is a channel/library/block that will give speed outputs or will do differentiation? Or should I write my own Qcode for differentiation?.
