Curtis 1238-1701 PWM question
In my controller, under the drivers menu: fault:PWM Freq.
The range is 20-500
Mine is set to 200
The controller will output up to 300
Why would it not be set to 300?
TYVM,Miz

Re: Curtis 1238-1701 PWM question
Don't change that unless you've changed the contactor from an LEV200 24V coil contactor to something else.
What menu Item is it? I can't find which menu Item you're looking at.
Drivers menu
-Main contactor
-Proportional driver
-Hydraulic contactor
-fault checking
???
What are you trying to do? Why are you trying to change anything?

Re: Curtis 1238-1701 PWM question
I have a controller fault. 43 (red-yellow-yellow-yellow-yellow-yellow followed by red-red-yellow-yellow-yellow)
secondly, I have a throttle problem, it only runs the motor to about 1100 RPMS at full down.
I have another error message W0048. under 2torque mode, speed limiter, maximum speed.
My supplier told me he had done "some custom programming", but I was not given any list or other explanation.
One of my past jobs was with a factory race team, I managed the fuel, spark advance and traction control mapping. This is pretty straight forward.
Question? How does the PWM setting affect the contactor. It isnt in it's section in the tree.
It was in the drivers menu under fault checks and PWM freq.
I will pull it up again tomorrow and see if I have missed a step in the drill/down.
thx
Miz

Re: Curtis 1238-1701 PWM question
Drivers menu has to do with the contactor. Have you looked in the manual?
Take a screenshot of where you are in the menus... you're not making a ton of sense.
Get a hold of the person that sold it to you and see what they changed... who'd you buy it from?

Re: Curtis 1238-1701 PWM question
Yah, reread the manual lots, I even have the print out of a HPEV original set up to go by.
I was just curious about that frequency deal..they have it set that way also.
I have noticed a couple of mislabled items. The manual and my controller have a different term in 2 places. Not surprising.
The more I read through the controller, the better I am getting at understanding it.
BTW: I still have that 43 error flashing on the controller. I am really trying to cure that. Brake wiper high signal. Nothing is hooked to that pin though...?

Re: Curtis 1238-1701 PWM question
What is the Pot 2 wiper voltage?
Look under Monitor - inputs - pot2 raw

Re: Curtis 1238-1701 PWM question
Isn't the original seller helping you? You should really be going through him if you have errors or problems with the controller.... that's part of why you pay them, for support.

Re: Curtis 1238-1701 PWM question
I am still getting that 43 error code from the controller.
I have pretty much checked everything in the controller against a known good set up sheet.
The controller is flashing red yellow yellow yellow yellow, red yellow yellow yellow. (43) "Pot 2 wiper signal high"
I went into the section and looked at the controller real-time values and Sure enough.... 6.24 Volts on pin 17.
Well, if I keep the brake enable shut off, Everything works well (except no regen of coarse)
I have wires from pin 17 and pin 18 but there is nothing attached.
I tried all 5 types of throttle pot 2 settings, same thing.
I tried a 2 wire pot connected and all 5 settings, same thing.
I tried both wires connected together as one would expect for a signal from a 0-5K Ohm pot at rest, same thing there too.
It keeps merrily blinking that error code.
BTW: I am cycling the key switch after every parameter change to assure the controller is resetting positively.
I am not giving up and am still at it this morning.
I will keep checking this thread through the day in case someone has a brain storm.
Thanks, Miz

Try shorting pin 17 to pin 18. That should take pin 17 (brake wiper) to zero volts.
