yes, logic come on when I power up cabinet, e stop does not engage until oak board runs thru startup sequence. DMM thinks initial amp requirement is too large to put contactors in and have drives come on one at a time. But I have a 30 amp breaker on system and it does not trip. I have also unplugged motor power from other two drives only powering up 1 drive. still get alarm. but I can power up motor power on all three thru a standard surge protector strip on 110v and system will not alarm out for over current/ Voltage. ?
