Problem with Regen

Hello,

i have an 18 Fet Controller (Board Type EB318-AS-3)
i used the keywin software but regen braking does now work.

e-brake cut off works, if i hold it i can hardly turn the motor backwards. it also cuts off acceleration when i press it.
regen jumber is enable
EBS Level 1 and 2 tested with all EBS Limit Voltage.
Akkupack 72V LiFePO4 (also checked with another pack)

can anyone of you help me?

BR Michael

thanks god for xpd.

problem solved

?? how did you solve the problem??

i do not know what the problem really was, i think it was something with regeneration voltage.
with xpd i send the same setting as with keywin and then it worked.
