MD4 functionality after screen crack
Say the MD4 screen is broken or cracked, would the I/O and CAN messages still work on the module, assuming no damage to the board in the enclosure?
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
Voltage input to MC2 from an amplifier
Hello Team,
I've been working with potentiometers and parker sensors (pressure and temperature) before without any problems, but now i need to use a voltage output (0-5V) from an amplifier as a voltage input on my MC2. The amplifier is connected to a sensor and have a standard +- output. I've tried to connect + to one of the VIN-x and neg to -VREF (or to the common terminal on the power supply). Tried different combinations but the measurement mode on the MC2 shows zero input all the time. Multimeter measurements confirm that the amplifier output around 1V. Logically don't see why it should now work, but maybe you can advise how 3rd party sensors (amplifiers) are connected to parker systems? Thank you!
Startup Multi-Master
If an application have a MD4 and MC4X and they are connected as multi-master. How does the startup looks like? Will the MC4X start communicate with peripherals as soon its booted or does it wait until MD4 is booted?
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.

MD4 +RTC RESISTOR
The MD4 documentation states to use 1.5K ohm resistor on the +RTC circuit. Is the 1.5K ohm the only type that is usable, or is there a range that will work?
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.
