    how to program a sevcon gen4

    There are different models of the PMS 120, I could share the manufactory standard values of a 72/80v 10,5kw water cooled version.

    Doctorbass Zero S mod to 2013 motor

    From my experience, I compared Cycle analyst readings with gen4 data logging and there was a big difference.. I do trust more the gen4 and did not manage to draw significant more than the rated boost current.

    Doctorbass Zero S mod to 2013 motor

    Question 1, what happens if I use a motor, with lets say 70kv, and I want to spin it with 60v battery to 6000rpm? Question 2, what happens if I set torque target to 115nm and go into field weakening the same time?

    Doctorbass Zero S mod to 2013 motor

    I don't want to give some wrong advice as I don't know your exactly setup, but I had some trouble with the thermal cutback. Imagine the Sevcon not only measures the actual temperature via the temperature sensor, it calculates an temperature that "should" be more realistic. The temperature sensor...

    how to program a sevcon gen4

    Try to upload your stock 12" dcf with "send dcf to unit" with 500khz, after upload you should be able to communicate with 125khz again. Than just remove the ixxat and open the 13" file in dvt, there is something like "manipulate offline" or so in the helper menu. There you can get all the...

    how to program a sevcon gen4

    This does have another reason than the voltage. Does the Led on the Sevcon blink? Did you try to change the baut rate? I am not sure but maybe they changed from 250kbs or 1000kbs to 500kbs from "12 to "13. Try this at first, if the Sevcon led is alive, this will be a canbus error..

    how to program a sevcon gen4

    You can do both. Open the file "offline" and see some values, or you simply open it in any text editor and search the values you are looking for. Then you need to convert from HEX to DEC and sometimes multiply with an factor (for example for voltage 0.0625). All those factors are also included...

    how to program a sevcon gen4

    Its for communication between different Gen4 or other devices. Is your Gen4 used or new? Looks you need to setup the canbus correctly.

    why shouldn't i assume it should work??

    Hi, the kv should be around 80, it`s a rewound C80100. Voltage is 80V so the lower rpm would fit. The 6A/15A are a bit to high, because I messured with a planetary gearbox on it. Controller is 18FET Lyen mod.

    why shouldn't i assume it should work??

    Hello, to make it a bit more clear for me and maybe some others. When you say 3 good forwards and 3 reverse, does that mean for me each hall combo has one correct one, true? Lets say I have 3 runing phase combos in one hallorder, 1 is noisy. Two stay. 1 runs in one direction drawing 6amp at...

    Sevcon Gen4 Problem - any tips?

    Hekko, I bought the IXXAT usb-to-can from Heinzmann. http://www.ixxat.com/usb-to-can-compact-interface_en.html I had the biggest problems with the can-settings, i/o was easy, motor has a lot of parameters, you should have a similar setup to start from.

    Sevcon Gen4 Problem - any tips?

    Hi, I do have settings for the motor and encoder but I think they don`t match the Brammo stock settings. The encode needs to be set up individually with every motor. There should be a script for doing it with the dvt software, but I dont own this. If you like you can have my motor settings.

    Sevcon Gen4 Problem - any tips?

    Hi, now the controller works, it was set of problems, when I tried to change some parameters with dvt and stored them they were gone after recycle. I had to change all currupt parameters at one time in the dcf file and upload it than. After this it worked. Strange behaviour of the device...

    Sevcon Gen4 Problem - any tips?

    I eliminated the source of the encoder fault and found that the node-id was 0, range is 1-127. This caused the internal fault. After this i have no fault in pre-operation mode. So far so good, but than i set to operation mode and recycle key, i get a HeartBeat fault from the canBus, LED flashes...

    Hello again, today my canOPEN device arrived, I made a cable and was happy to be able to connect with the Gen4 again. I have 4 faults displayed in the attached image. faults: #0 & #1 i should use 5621h to identify the object being out of range, how is this done? #2 check encoder wiring -...
