view angle MD4 with part number 20085164

Laura 3 years ago in Master modules / MD4 updated by Gustav Widén (System support) 3 years ago 1

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

Sluggish touch response MD4-5

Kevin 3 years ago in Master modules / MD4 updated by Gustav Widén (System support) 1 year ago 8

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).

How to calculate speed of a BLDC motor with quadrature encoder

Vignesh Namasivayam 3 years ago in Master modules / MD4 updated 3 years ago 2

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?.

When using the MD4-5 in portrait mode are the large C1 & C2 connectors at the top or bottom of the module?

Touchscreen issues

Ethan Zeman 4 years ago in Master modules / MD4 updated 4 years ago 6
I have seen increased reports of customers who have had to replace MD4s due to failed touchscreens.  The MD4 will still work fine but the touchscreen will quit responding.  I've had a few returned for review and it almost seems like the screen is delaminating (see attached photo)?

Most have occurred after several years of operation so not particularly early hour failures, but I would still expect a longer life from a touchscreen (my phone for example gets much more use and abuse).

Just wanted to put this out to see if others are seeing the same issue or if Parker is aware and has made any improvements to the screen over the years?

MD4-10 - Axis Video Encoder M7011 -MJPEG link for 4.07

Damir Pinezić 4 years ago in Master modules / MD4 updated by Gustav Widén (System support) 4 years ago 7

Hi all,

I have read all forum topics which include connecting IP camera to the Parker MD4, and try almost every combination of URL and still didn't found the right one.

Does anyone knows what URL should I use and maybe why I could not get stream from this Axis Video Encoder(M7011), it states in datasheet it suppports MJPEG and with VLC I can connect and stream rtsp but when I check in VLC stream info it sjhows that it uses MPEG4.

1. I have set right ip addressa and subnet mask 192.168.128.xxx/255.255.128.0

2. I have enable anonymous access on Video encoder

3. use every possible link I could found (axis-media/media.amp, axis-cgi/mjpg/video.cgi, mjpg/video.mjpg)

Is it possible that this video encoder does not support MJPEG even if it states this in documentation?

Does anyone have experience with this video encoder model?

Thanks!
