Drive Capacity - YASKAWA E7N Technical Manual

Drive Capacity

Parameter o2-04 sets the Drive capacity according to the model number. Parameter o2-04 will need to be adjusted when
replacing a control board.
If a Control PCB is changed, the first time the Drive is powered up, parameter o2-04 must be set to the appropriate value listed
in Table B.1 for the Drive model number. After properly setting parameter 02-04, a 2-wire or 3-wire initialization must be
performed by setting parameter A1-03=2220 or A1-03=3330, respectively.This will automatically program the values of all
other parameters listed in Table B.2 to the factory settings for that particular Drive rating.
