Hi,

I'm relatively new to the IQAN system. I'm currently using the MC43. Is it possible to have high side digital signalling outputs? I'm interested in controlling some industrial devices that accept 24V digital inputs. From what I understand, most of the digital outputs have some sort of fault detection on loads lower than a few hundred milliamps. The only way around it I found is to use PWM outputs, which are limited and also seem like a bit of a hack.

Would be great to know if this is possible.

Thanks! 

Not sure if HS PWM output circuit support the open load detection, we used pin 45 on MC41, any current measurement capability on this port. If yes, how that can be monitored from the IQan software.

Thanks 

I am working on the control system using MC43. Please let me know urgently whether I can use MC43 ‘PWM out HS+LS’ or ‘PWM out HS’ to control Danfoss PVES or PWEM proportional solenoids 

From MC43 instruction book:

From Danfoss solenoid specifications

I need to know what are the possibilities to connect MC41 controller with PC to flash program into controller and for diagnostics.

The MC43 documentation states to use a single 40A external fuse to protect the module. Is it sufficient to run two single 20A fuses, one on each +BAT connection?

Hi,

We have installed a speed sensor (PNP, 15000Hz) onto a MC42 frequency input (pin C1:28, PD).

The problem we have is that the raw value only goes up to about 2800Hz then zero's out with no further reading and we need to get a reading up to at least 5500Hz.

I have configured the input settings to: Max HZ -> 15000 and also the Scaled Maxed-> 15000 to mach the sensor's capabilities and then use the raw reading to scale a RPM value.

We tried adjusting the sensor closer to the ring gear, but no improvement.  

So I did a test to see if it might be the sensor that is faulty by connecting the sensor to a different type/brand of controller. It immediately worked and gave the correct reading constantly.

The question is now... What am I doing wrong on the IQAN side? 

What can be the cause of this error ?

I have a MC43 with the following blink code 4 red, 2 yellow, 1 yellow, 1 yellow, 1 yellow. What do the 3 yellow blinks at the end mean? This happens intermittently when the module first gets power.

I am considering using an MC41 with PWM signals as inputs. These signals come from joystick thumbwheels on excavators made by a large multi-national OEM. My problem is the spec on the frequency of the PWM signal from the thumbwheel is 500Hz +/- 50Hz. I see the max allowable frequency from the MC4x catalog is 500Hz. Wondering if the MC41 will work with 550Hz PWM frequency input.

How this can be done? Did not find from channel properties.
