Bafang BBSHD no response in PAS 1

[laudou]

I have this BBSHD motor with a 48v. 21 A battery that is getting no assist at all in PAS 1 out of 5. Be it in Eco or in Sports mode, no assist at all. The PAS levels from 2 to 5 are working normally. Or is there a special way to program a 5 PAS levels DPC 18 using the 9 PAS level config tool available on the net? I only used data for the first 5 PAS levels, leaving the last four blank. Could that be what caused PAS 1 not to output any power? Where should I look?

I eventually replace the original 5 PAS DPC18 with a 9 PAS-860C and the PAS 1 problem went away. I gues the culprit was the display.
Thanks

I know. And when I long press the + I enter the Sports mode. Long press the + sign again gets back to Eco mode.

I was thinking that you have the newer ‘upgraded‘ model. Mine is about 21 months old. But seriously why did the bother?

I'm not sure I understand your question. Anyway, I replaced the DPC18 that came with the bike because PAS1 did not work.

The question was why did they bother to change from the simple numerical PAS system to eco/sport? It's not addressed to you.

As you certainly suspect, I have no reply to your question.

I don’t understand what’s confusing about a model of display potentially having different firmware.

Why did they lock out 52V batteries? Why did they change the BBS01-02 and not inform their dealers? Trying to sort Bafangs logic will just get one's head spinning.

Tom, I have a 52 volt battery. What exactly was locked out? They say the motor is rated 48v/52v btw.

For a few months, we saw BBSHD firmware that would not recognize a 52V battery. Using a 52v battery would give error code 07, overvolt, and not run. Mind this was more than a year ago.
