Parameter E 3 - 0 1 determines which control method the drive will use when motor 2 is
selected. If E 3 - 0 1 is set to a 2 or a 3, the second motor needs to be auto-tuned. First
select motor 2 (via a multi-function input) then run the auto-tuning routine as described in
Section 2.2A or 2.2B. Parameters E 4 - 0 1 thru E 4 - 0 7 and E 5 - 0 1 thru E 5 - 0 6 are set
when an auto-tune is executed on motor 2. If auto-tuning is not possible, use section 2.4
and the table below to manually calculate and enter the motor parameters.
