I have an issue where the camera drops out when i run an extension ethernet cable between an SV camera and an MD4. My extension cable does meet Ethernet standards for twisted pair. Any suggestions are appreciated with helping to resolve this. 

Hello,

I need to drive relays on low side outputs on the XC-23 and MD4-5.  Do I need to use relays with included coil protection diodes or if the outputs of these modules are already internally protected ?

Thanks,

Guillaume

Hello,

I'm wandering if I could use two(2) or more low side outputs in parallel on the XC-23 to increase the carrying current capacity from 300mA to 600mA (2 outputs) or more.  I have a relay that I need to drive that needs more than 300mA.

Thanks,

Guillaume

I have a project that uses one MD3 and one XC10. The XC10 sits on its on Expansion Bus CAN line with no other devices except for the MD3. Occasionally, during startup the XC10 will report multiple address.

Currently we tell the customer to power cycle the machine if this comes up and it typically goes away. I am looking into automating this if possible. I have tried a few things and have not had any luck. Is there a way to do a forced reset either on the MD3 and/or XC10 to try and reset the error?

Right now, the XC10's V+ supply is behind a relay so I can cycle it power directly. Testing this method has also not panned out.

MD3 cycle time is at 10ms. I read on a different forum post that the XC10 can only go down to 20ms. Ideally, I want to keep the cycle time as low as possible because of how the machine operates. Would going to 20ms help with the multiple address issue?

Are there any othe XC10 limitations I should know about?

Is there anything else I can experiment with to try and resolve the multiple address without the user’s input?

Hi ! 

One of my OEM wants to drive SAUER 90R075KAS (servo EDC, 14-85 mA) with one current output with our IQAN MC43FS. 

I know that the mC43FS has a new functionnality , but I am not sure for this kind of current…. ! Please feel free to contact me if you have one solution…. Best regards. 

Why do the XA2 and XC10 manuals call for adding clamping (flyback) diodes to digital outputs?

From what I can gather, the modules are equipped with their own internal clamping diodes. Why would those be disabled for digital outputs?

Thanks

I have come across an old machine that has a HBC Remote Receiver which is connected into an MDL2 system using the XR expansion module. The proportional Inputs from the remote are configured as Voltage In and from the view point of the IQAN system operate from 0 to 5 volts so every time the proportional paddle is moved to full stroke in either direction a system generated error is produced and the input is turned off. Has anyone come across this problem is there a simple solution. The HBC suppliers say that can't change or scale the outputs from the receiver.

I am trying to design a system with redundant MC43s controlling the same components on their COUTs and DOUTs. Only one module would output at a time. Could this be accomplished without using relays? Can Diodes be used to prevent one backfeeding into the other? What is your suggestion?

Would any problems arise from supplying Parker Pulsar valves with a digital out signal instead of a PWM signal if proportionality is not desired? We're using an XA2.

Would a clamping diode be necessary in this configuration?
