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?

I am having problems connecting to a MC42FS.The PLC worked fine last friday but when trying to upload some weekend changes this morning the PLC suddenly stops working. On the first programing attempt after power-on the programing process stops at "stopping applications" followed by a "no handshake replay". Trying to program the PLC after will only result in a "no handshake replay". If connecting to the PLC after cycling the power with IQAN run i get the following error. "There is no valid application in the target module. Error code R4:2 1:1:1 (Int.diag error(Backending?)) MS42FS[NI address tag] (FW version 6.04.4) i have tried multiple times with and without the ID-tag, but nothing changes. Any ideas on how to get it working again? 

How is the performance proportional pressure control devices, such as a Parker RE06 without on board electronics, using Parker MC4* current output channel? The Parker industrial driver, PCD, uses a 10kHz PWM frequency to drive an RE06 coil. The Parker MC4* has a current output PWM frequency limit of 500 Hz. I have driven an RE06 coil using Iqan products in the past without noticeable performance issues, but wanted to see if others have done the same.

Thanks

4 red flashes, followed by a yellow flash sequence of 2-2-1-3

This continues to happen when trying to start the engine of the machine. As if maybe the battery voltage is going too low momentarily.

Once in this state, the IQAN module cannot be communicated with using IQANRun 5 and is not operational until powered off then on, but will deliver the above flash sequence. 

Any help would be appreciated.

Hi all,

I'm currently testing an MC43 on our HIL bench and notice some issue with the low side driver at startup.

On our system, all the low side driver of the MC43 at pulled up to supply voltage with a 10K pull up resistor.

The problem is that when we switch on the ECU, it's going into error with the code 4:2.

We find out that by waiting 1.5 sec at startup before pulling up the low side driver fix the problem. 

The problem is that on the vehicle we will probably end up in this situation as some low side driver are going to be pulled up throw some relay coil. 

Is the unit is going into error if any low side driver is pulled up or only some of them trigger it ?

Thanks for your support,

Grégoire

I am trying to read a NTC thermistor with a resistive output ranging from 810 - 76.9 ohms on the MC43. 

In the past we have used a voltage divider circuit to read the sensor value on a VIN channel, but if the MC43 could introduce a bias current to the thermistor then the output voltage could read without the need for a second resistor in the mix. 

I did not seeing any mention of this in the MC43 manual but was wondering if anyone has faced this challenge before. 

Thank you. 

Hello,

We are currently working with a MC43, and I had a question regarding the use of PWM out as a control device. I found this post, since it was 4 years old thought I would ask again. We are trying to control a water valve position with one of the PWM out on the MC43, but not getting the expected results. 

The datasheet specifies a leakage current of 2mA. What do you recommend to clean this up and bring it down close to 0?

I am relatively new to the whole IQAN infrastructure and I am wondering why is there such a high leakage current? Is there any benefit to it?

Thanks in advance

Is there any reliability data for these modules (non failsafe versions)? We are using modules for control system functions and to see if they comply with basic performance levels (b). Is there any documents that are available showing MTTF of these modules that can assist with calculations?

I see the manual includes this:

IQAN-MC4x performance only runs a sub-set of the MC4xFS functions for internal diagnostics. Because of reduced diagnostics, DC and thus SFF and PFHd is not available for these modules.

But we were able to get reliability data for XC2X range at one stage even though this was not a safety controller, is this likely to be possible with the MC4X?

Tjena.

Är det möjligt att koppla en G11 med Iqansynk mot en MC41, har en MC41 som "standalone" i en maskin och vill redigera vissa parametrar för att se resultatet "live".
Om ja: vart ska den in? (stift)

Om nej: synd...
