Kflop+Kanalog cyclic restart

Post by Andrej » Sat Aug 11, 2018 3:47 pm

Hello,
When Kanalog J12 is connected to Kflop, Kflop restart for several time, like this:
Kflop LEDs have blink after restart, then Kanalog LED has blink and turn off, then Kflop restart also, ...
It is for USB and external 5V supply, where on the Kanalog board we see: 5V is 4.6V, and 3.3V is 3.15V.
Sometimes cyclic restart stops, and there is Kmotion conecting with Kanalog parameters.
Thanks!

Hi Andrej,

This can happen when:

#1 - trying to use USB power
#2 - +5V external power supply is too small
#3 - long thin wiring used to the +5V supply

The supply should be at least 4.75V (ideally 5.0V) and rated for 2 Amps or more.

Kanalog has a +/-15V generator that starts when Kanalog is enabled that creates a current surge from the 5V supply. If the power supply can't handle the current surge, the voltage drops, and KFLOP resets.

HTH

Thanks!
LED is on.
JP12 pins 25 27 +/- 15V voltages.
