phaserunner settings for dummies

Post by goatman » Jan 24 2020 3:51pm

the phaserunner has autotune when you initially install the controller but there are many more settings. like virtual electronic freewheeling, torque ramp up and top speed overdrive.

ive searched but I haven't seen a dedicated thread that shares the settings for their particular set up.

regen amps, if I set my regen at 20 amps but my batteries can only handle 4 amps per cell at fast charge, my pack needs to be 5p but if im only 4p my regen amp settings should be 16 amps not 20 amps. or are the regen amps measured in phase amps and not charging amps to the battery.

my CA showed 400 watts at full regen braking, my battery charger at 70 volts and 5amps is about 350 watts. I have a 4p pack so 1.25 amps per 25r cell

so the regen setting in the phaserunner at 20 amps is the same as my charger at 5amps? ill start sharing my settings as I figure them out.

If you look closer, there are two separate settings for regen amps - "Max Regen Phase Current" in the 'Motor Limits' section, and "Max Regen Battery Current" in the 'Battery Limits' section.

Set "Max Regen Battery Current" to what you want to flow back into the battery, then experiment with the "Max Regen Phase Current" setting to get the braking performance you want. If you want maximum regen strength, set the "Max Regen Phase Current" to 96A.
virtual electronic freewheeling
This takes a bit of trial and error. Start by setting it to something very low, like 0.1A, then lift the wheel off the ground and give it a tiny bit of throttle. If the wheel slows to a stop too quickly, set the freewheeling current just a little higher and try again. On the motors I've tried, it took anywhere from 0.3A to 0.5A to make the wheel behave roughly like a normal freewheeling bicycle wheel, which is the idea. But if you want, you can take it a bit beyond just 'freewheeling', to give yourself a bit of constant, passive motor assist.
torque ramp up
Higher values will make the motor accelerate more gently, while lower values will give you more immediate throttle response.

Worth noting, if you hover your mouse over most of the settings, you'll get a tooltip explaining what the setting does, and some of them have suggested values to start at.

im just going to edit this as I change settings if that's ok?

crystalyte hs3540r
17s4p with 20amp 25r cells
26 od tire

max power 3000 watts
phase current 96a
regen phase current 31a

battery limits
max battery current 58.9a
max regen battery current 16.1a
max regen voltage 71v
max regen start 69.5v
lvc start 51.5
lvc end 49v

feedback bandwith tuning
I haven't touched these settings

virtual electronic freewheeling

I was just playing with the electronic freewheeling, with bike upside down and 1.5 amps of electronic freewheeling current. I touch my throttle and let go, my tire will continue to spin at a rate of 1 revolution every 1 second. once I touch the regen button the motor stops. my DD hub now pedals easily at walking speed and you can probably walk with the bike

makes me think with the phone app you could make this a poormans cruise control for highway trips. up the amps to 10 or whatever and away you go, touch the regen/brake to stop/disengage it, then throttle to re engage it

output torque ramping

torque up ramp I changed to 60ms
I didn't touch any other of the settings

top speed overdrive

I haven't touched yet, the bike is already doing 60km/h wich I rarely do but sometimes I need 65km/h to get into traffic to make a left turn.

just in the few short trips ive done, 60ms the bike is faster on the throttle with a light feeling on the front tire under throttle

31 regen phase amps/16.1a regen battery current gives 750watts of regen on the CA and 10 to13% of AH.

any suggestions?

So the battery limits are the settings in the Phase runner, ie 58.9a.
just wondering what the limits are in the settings. I know you would need to add heat sink if ran at the upper amps.

58.9amps I set in the phaserunner. im not wired to be pulling more amps than 60. amps/phase amps thermal rollback heatsinking. is a bit too much for me. the most watts I pull are about 2400. this setup reminds me of a 40 amp infinion 12fet with 4110s but I could only get 400 watts regen and it wasn't adjustable.
riding it hard was 27wh/km but speeds were high 50s uphill then max regen downhill. it was abuse testing and nothing got hot.

top speed overdrive

field weakening current, if I put in 2 amps of current, when does it start? always?

I wanted to know my top speed.
I went on a quick trip of 10km. fresh battery going up a slight grade I maxed at 65km/h, coming back but going down same slight grade was 65km/h. that's my max speed I guess.

65km/h is the max speed I rarely use, when I use it, its so I can hop in traffic to get into a left hand turn lane.

how can I set this so it only kicks in at 55km/h?

I put my regen battery amps to 30 and I get about 1400 watts regen and I noticed the sidewalls of the rear 24x3.0 kenda flame are showing signs of stress. theyre crappy tires but im also worrying about the spokes and clamping torque arms. if I change the Regen torque engage ramp from 200ms to 400ms will that ease the impact when hitting the regen button? its not a BANG I just want to lessen the force of engagement at high speeds while keeping the regen amps high
