5.20 Menu 21: Second motor parameters
The following parameters are used instead of the normal motor set-up parameters when Pr 11.45 = 1.
When the alternative parameter set is being used by the drive the decimal point after the right hand digit in the 1st row is on.
Unlike the motor 1 (Pr 1.14) this parameter is not used for T28 and T29 digital input auto-selection (see Pr 8.39 on page 151).
Pr 21.03 defines how the value of Pr 1.49 is derived as follows:
*The bit Pr 1.41 to Pr 1.44 can be controlled to force the value of Pr 1.49:
all bits equal to zero gives 1,
Pr 1.41 = 1 then Pr 1.49 = 2
Pr 1.42 = 1 then Pr 1.49 = 3
Pr 1.43 = 1 then Pr 1.49 = 4
Pr 1.44 = 1 then Pr 1.49 = 5
