RGBL1860 motor current problem

Hello, I would like you to help me please,

-The problem is that the controller RGBL1860 measures a motor current and a battery current too high compared to
another controller RGBL1860 for the same motor with the same speed, knowing that the control law is Trapezoidal,
for example for a speed 1000 rpm, we have motor current = 25A and battery current = 8A
for another controller, we will have, motor current = 17A and battery current = 5A
can someone tell me the possible cause of this problem ???

Please help me to locate the electronicscomponents that can cause this problem in both cases !

Hello @Ebram
they haven’t answered you yet !
I think the problem is the calibration values of the current sensors which are configured with the commands ~ zpac and ~ zaic … etc
can you ask them these values for the controller RGBL1860 ?!

Hello @moh,

Yes, we haven’t received a reply from them yet, we left another reminder yesterday so hopefully they will reply soon.

We will add this new question to the email.

Hello @moh,

Sorry for the late reply.

We have finally received a reply from the manufacturer:

Please ask customer to check ZPAC values from console. The steps are -

  • Go to Console (Roborun+ App)
  • Give command “~ZPAC” and send
  • report back the output of it.
  • If firmware is 2.0+, then ZPAC value should be close to - 1702 : 1806 : 1815
  • If firmware is 1.8, then ZPAC value should be close to - 1098 1193 1715
  • Check ZPAC value of the controller which is working correctly.
  • How to Change ZPAC values - (Only If firmware is 2.0+)
    • ^ZPAC 1 1702_^ZPAC 1 1806_^ZPAC 1 1815
    • %clsav 321654987
    • %reset 321654987
    • Verify ZPAC values are changed with ~ZPAC

Let us know if this fixed your issue or if you need further assistance.
