I use Grin components including GMAC motor, Phaserunner and Cycle Analyst on my wheelchair power drive. It’s a great setup but I’m definitely ordering a Superharness and the 750C display because it will just make the whole setup a bit tidier and more compact for when I have to load it into the car. Looks like another great product. 👍
Congratulations for the nice video, as always your products and information are of high level. Instead of a KM5s, I connected an Eggrider display with ASI protocol (baserunnerZ9-V6 with only PAS sensor, without superharness because I do not use throttle, regen and lights). After adjusting various parameters via "Suite" everything works fine, however after about ten minutes of good operation a "communication error" appears. Could it depend on the lack of superharness?
Nope, the superharness plays no role in the communications between the display and controller and wouldn't make any difference, Tx and Rx just pass right through. In your case (since you don't need the proportional regen control) there's no need to get it. You might however find that the communication is more reliable if you connect the eggrider to the TRRS communication port instead of the Tx Rx on the Main9 plug.
@GrinTechnologies Very interesting, thank you very much!!! I was thinking of trying the ASI "remote control" mode (serial streams), do you think it could work?
Assuming it is a conventional hall effect throttle with a 1-4V signal range when powered from a 5V supply, then yes. Up to you to figure out if that is the case and what the pinout is. A multimeter probing your existing setup would be informative in that regards.
I mean you could use it as a throttle, or you could use it as a proportional ebrake if you jumper closed the digital ebrake input line whenever brake lever is squeezed with a limit switch or such.
I'm glad you've added this option. My guess would be that going from CA3 to Superharness means you lose the throttle "autocruise" and 3 preset options (which I believe are CA3-specific features)?
Yes indeed, and things like back pedal regen, regen enforced speed limiting, wh/km statistics and all of that. So it's not an upgrade in terms of features, but for people who don't need those features and care more about having a color display this should check that box! The different assist levels can be configured in a similar way to presets though, so if you do set it up for 3 assist levels each one can have its own independently set speed limit and power limit.
These multi pin round connectors have an embossed arrow that is never in different color and hard to see. If the pins are not aligned, it's so easy to break them.
Yup, it's a pretty bad design, but became a defacto standard that is now widely available. Even more silly is that the pin positions line up in the different pin count connectors, so you can mate incompatible plugs together. Higo has other versions with geometric shapes so that they can't be misaligned, but they are seldom seen in the spare parts market.
Also the 8 pin plug on the Phaserunner doesn’t actually have a notch, so alignment of the pins is all you have to go by. Personally I’ve marked the alignment notch with a small grove on the outside of the plug so it’s easy to see when they are aligned.
@grintech. I had to run my Brompton superharness kit as sensorless to get rid of the display errors. Do you know how i can run with the default hall sensor setting?
Try gradually reducing the maximum phase current limit and you should find a sweet point that still gives good torque but doesn't result in electrical noise causing the error 30. Or if you only see this at low speeds starting off, try having a much more gradual speed limit ramp time, like 3000mS
questions, do you really need the Superharness? cant the phaserunner be connected directly to a display? Doesnt phaserunner have all the connections for PAS, Brake and ADC1/2? I wish the super connector had a PAS input that would make it useful for anyone running a VESC or high power controller that doesnt support PAS.
My understanding may be out of date on this but I've been told that while there are all those connectors for the phase/baserunner they can only be used with extremely minimal programability and adjustments and no regen.
ebikes.ca/shop/electric-bicycle-parts/controller-accessories/diy-main-harness.html If you know what you are doing, but there is no way to have a torque sensor, throttle, and variable regen. You can use the CA3 to add torque and PAS control to a vesc no problem
what I would like is a "super harness" that would tidy up the octopus thats hangs out the back of my ca3 not a colour screen thats gives you little to no information and the loss of the ca3 control and settings. I had to cut all the wires and shorten them, then solder the throttle brakes etc so not to have the bulky connectors. love the ca3 and the phaserunner but the loom/harness needs work
Did the strechy fabric sleeve not do the job OK? Usually that can conceal the cluster to a satisfactory degree. At one point we actually designed a hinged plastic enclosure box to cover all those connectors and got the mold tooled up, but we didn't do a good design on the plastics and so the hinge and snaps would easily break, and then dropped it. Agreed that it's an area that could use some attention but it's been kept that way for legacy support.
@@GrinTechnologies I felt the fabric sleeve was an after thought as in "that will do" to cover the mess of cables. It's not a long term solution thats looks aesthetically pleasing. please revisit adding a box or enclosure to the top or back of the ca3 as and add on part ie you can buy it if you want it that would enclose the octopus and still allow "legacy" builds. your halfway there you know how not to make it from your previous attempt. i'd be happy with a hollow open top box with a seal that screws to the back of the analyst with a bag of grommets and drill the holes I need and fit the grommets. make all the connections then screw the box to the analyst with a rubber seal.
Yes, either by replacing the hub motor and motor controller, or by replacing just the motor controller and modifying your motor to lock the clutch so that the motor is always engaged and doesn't freewheel. Watch this video to get an idea of what that entails, it's not a simple job by any means ua-cam.com/video/sL3bjQZGjoQ/v-deo.html

Love the snark in this video.
If I have a surron throttle can I wire the three wires to higo plug and use this kit with a Phaserunner on my ebike. That has a hentach motor

The analog brake levers can be used with CAv3 if you don't use a throttle right?
I mean you could use it as a throttle, or you could use it as a proportional ebrake if you jumper closed the digital ebrake input line whenever brake lever is squeezed with a limit switch or such.

@@GrinTechnologiesthanks, just confirming, and I understand the display desires. Glad you offer the choices.
@@GrinTechnologieswill back pedal Regen be available in full release firmware soon, as opposed to just beta?
I love everything you are doing at Grin but wondering if there will be a new app coming for the phaserunner
And if so will there be IOS as well:)

I actual get a 24H error that won't go away. Is it still the same fix?

@@GrinTechnologies Figures.
Does it support 72v?
Yes it does! All three of the displays we got were customized for 72v support, and the front/rear light controls work at 72v too.
Wow, that's great!
But, I mean, who doesn't want all the numbers and data!
I hate JST connections with the fire of a thousand suns.
thank you.
