MC43 PWM out
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

Generally driving Danfoss PVG valves with IQAN Control system, we advice using the PVHC control option from Danfoss. You can drive the PVHC direct from the IQAN COUT current control output, Simple and works well.
Ratiometric input signal requred by PVEM series cannot be controlled by IQAN available Outputs, same for PVEP PWM signal controlled modules as they have high input impedance (5 kOhm), requiring extra Pull-down resistors to connect to IQAN PWM output
Another, more expensive, option is using Danfoss CAN control module PVED series, then need to include CAN protocol in your IQAN application
Conneting IQAN MC41 to PC
I need to know what are the possibilities to connect MC41 controller with PC to flash program into controller and for diagnostics.
You can only connect via CAN to a MC41.
So you need to have a USB to CAN interface.

MC43 Fusing
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?
Frequency input MC4xx
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?
MC43 VREF error Value 0.00 V
What can be the cause of this error ?
MC43 Error Code
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.
If it's occurring on start up, the likely causes are battery voltage exists on an output before the module powers up or a slow rise in power supply voltage. Possible causes are covered in appendix B of the instruction book.
PWM Input with frequency >500Hz
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.
MC41FS Digital out HS disabling under current shut OFF
How this can be done? Did not find from channel properties.
You find the property on the pin in the module view.
MC41 restart after low supply voltage event
I am using MC41FS in non safety application. During cranking voltage drops, but not low enough to reset module.
Module hangs up and stays that way until power recycle. Can I restart application back up with SW?
Current output 15-85ma - Possible with MC43FS?
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.
