Minimum configuration to get L210 running on the bench / how to initialise ISA shunt?

[tom91]

Post your params you currently have set.

Speed is MG2 for the IS300h, so try plotting that.

I am still convinced you got a wiring or power supply issue.

somehow I`m not getting further.

I have several issues:

The WIFI connection to the interface seems to be quite unreliable, sometimes parameters are not displayed, I have to reload the page often. Quite annoying, can I connect the Zombie via cable to my laptop to avoid having to use WIFI?

Sometimes the inverter does not come alive: when I switch on the Zombie and carry out the starting sequence, sometimes the inverter does not come up. I have to power cycle the Zombie then several times until it finally works...

And finally I still do not get this thing to spin. When I press the throttle very gently and release it again, the motor spins for one or two revolutions, but often in different directions (forwards / backwards). So I assume the electric power supply is sufficient to get it to spin, yet there is another issue.

I tried to shield the resolver cables by wrapping them in aluminium foil,... no difference.

@ Jacobsmess: regarding checking the reported speed of the inverter, I still did not find a corresponding spot value. Are you reffering to "speed" as a spot value?

Please post your params so I can go through and tell you what to change.

Does the output shaft spin freely by hand? Are you trying to spin 2 motors at once of have you set it to spin just MG2?

[tom91]

This was my test setup roughly a year ago. The comms cables are twisted pairs and shielded and so is the resolver cable.

attached are my parameters.

Yes, I can spin the shaft by hand, have to overcome an initial resistance (feels like magnetic force) but I assume thats normal.

If you do not find any wrong settings in my parameters, I will try a different power source and shielded comm cables...

I already tried to plot "speed" but it's a flatline. I assume "speed" is linked to the output shaft, if the shaft doesn't spin why expect any other value than zero?

Tried to spin MG1, MG2, MG1 & 2 and MG 1 & 2 blended, no success.

Please read and stop making assumptions.

How when and what. Did you plot it while spinning the output flange?

[tom91]

set MotActive to MG2
set regenmax to 0

Show all your spot values with the Zombie in RUN mode. Just save the webpage as pdf via print.

Yes, spinned the flange by hand as fast as I could, probably 60 rev / min... Plot showed Zero.
Inverter was in run mode.

[Bintang 5]

set MotActive to MG2
set regenmax to 0

MotActive set to MG2
regenmax set to 0

same behaviour:

spun the shaft by hand while plotted "speed" (inverter in run & direction foward):

I'll try to get some batteries now that I can draw more amps.

one more question, just found in my notes that there should be 60 Ohms between each sync serial wire pair (e.g. between CLK+ and CLK-) as a check if the wiring is ok. Cannot find the source of this information any more, I think it was in one of Damien's videos.

Where to measure that, is it the pins on the inverter side or on Zombie side? I unplugged the connector on the Zombie side and measured between the four sync serial pins/wires that run to the inverter. I measured 120 Ohms between each pair, not 60...?

[Bintang 5]

took three 12 V lead-acid batteries and connected them in series (36 V) as HV power source.
Basically same behaviour, the output shaft just rattles / shudders but does not spin.

I just realized that "idc" shows a negative value, is this correct or did I switch polarities?

here is a plot with idc:
