Grinfineon controller error code query

[danielrlee]

I'm probably worrying about nothing, but following a minor modification to my Grinfineon controller today (fitting an external switch), I have noticed a sequence of LED flashes that I don't previously recall.

When I turn on the controller the sequence is as follows:
2 quick flashes, 3 quick flashes, then a steady flash every 0.8 seconds.

I recall the steady 0.8 second flash, which as I understand indicates everything is functioning correctly, however don't remember the additional quick flashes before the mod. The controller appears to function okay with an unloaded motor, so there doesn't appear to be an issue. Chances are it's always done this and I'm just paranoid I've cocked something up.

Is anyone else with a Grinfineon controller able to confirm the same startup sequence? Thanks.

There may be different sequences for different controllers...but most likely any controller using the same MCU as yours would use the same flash sequences for the same errors. Thus, you may be able to look up the MCU number on the forum and find a matching code.
