Can PWM outputs be programmed to send 0-10Vdc signal?

Deanne 2 years ago in Master modules / MC4x updated by Pierre Fagrell 2 years ago 4

I have been doing some research and configuring a CANopen module to send a 0-10Vdc signal to run a prop valve. I have now been told that a PMW output on the MC4x and XC4x can be programmed to output 0-10Vdc. I wanted to confirm that is correct as I have seen in the forum that you are unable to send out that signal type.

Controlling 9V/2.7A prop valve with MC4X

Deanne 2 years ago in Master modules / MC4x updated by Gustav Widén (System support) 2 years ago 3

Has anyone tried to control a D1FBE01HC0NMWO (9V/2.7A spool) with a PWMOUT, if so what is the performance like? The rating for COUT is 2.5A so I will have to utilize the PWMOUT HS. I have read that COUTs allow the best performance with solenoid.

PWM Output - Doesn't Work with Low Current Load

ksilovich 2 years ago in Master modules / MC4x updated 2 years ago 2

I am trying to us a PWM HS Output on an MC4x to drive a signal needed for a PWM fan.  I will get an open load when I try to drive it directly, and even with disabling the open load check it still will not work. The output just stays at 12v.   

If I add a 1k resistor from the PWM output to ground, everything works as it should.   But now the issue I have is with no power to the MC4x,  I have some leakage voltage in the range of 50ma which will draw the battery down. 

Is this a software or hardware issue that will not allow me to use this PWM output to drive this fan directly??

My work around is using a relay to make and brake the resistor to ground when the MC4x is powered.  But this is not a great solution, and would like to see if this is just a software issue that could be fixed.

MC4x parallel HS output usage

Chris Litwin 2 years ago in Master modules / MC4x updated by Gustav Widén (System support) 2 years ago 5

When an MC4x DOUT HS is wired in parallel, are you able to drive a single output as long as the over current limit is not met? What I driving at is activating both outputs initially, and deactivating one later.

MC4x DOUT HS or PWM HS Over current threshold

What is the current level that triggers over current diagnostics when HS outputs are used in parallel?

MC43FS VRef+ no output

hongxiang yu 2 years ago in Master modules / MC4x updated by Gustav Widén (System support) 2 years ago 1

Have any idea what is problem cause VRef+ (C1:7) no 5V output.  I can comfirm the PIN and controller are ok after i made test on bench.

What is problem cause 5V PIN stop output. possible CAN wrong or Any PINs short to ground ? No error informs why VRef do not output now

4-20mA convert to V input on MC43 using 250ohm resistor

Kevin 2 years ago in Master modules / MC4x updated by anonymous 2 years ago 2

When using a high precision 250 or 120ohm resistor to allow IQAN to measure the signal from a current loop, do I need to connect Vref -VE for ground reference?

Any technical reason for using both +BATT pins on MC43?

Kevin 2 years ago in Master modules / MC4x updated by Gustav Widén (System support) 2 years ago 1

We have specified an MC43 over the lesser modules in the range because of the additional inputs we need to monitor in the controller. We are not using any outputs on the module therefore current draw is minimal.

Is the only reason there is a second power supply pin (+BATT) to drive the additional outputs that can be configured on the MC43? Because we are not using any outputs (therefore current draw is hardly anything) can we connect only one of the +BATT pin to the supply, is there any technical reason why this cannot be done? I don't have a module to hand but I assume they are internally connected? is there a current limit on the module outputs if we only connect one pin?

I have had a look through the manual, the diagram on page 58 suggests we need to connect both pins on MC43 module only.

Reading value of a PWM valve with a PWMIN

Andy Pauly 2 years ago in Master modules / MC4x updated by Gustav Widén (System support) 2 years ago 1

Hello

A stand alone system have 4x PWM proportional valves in 24VAD. I use a MC43. 

I like to ready this PWM value so that my system can give the right amount of oil from the variable pump. 

I like to use the PWMIN.  IN_33 and IN36 are for 5Volt sensors. Can I still use this INputs?? or do I need to use IN-37 and IN_38 because they are the only one rated to 24V. Can I somehow use a resistor so that I can use the 5Volt PWMIN.?? Sorry:  I am not sure even reading you documentation.
