When this bit is set to one the motor 2 parameters in menu 21 become active instead of the equivalent parameters in other menus. Changes will only
be implemented when the drive is disabled. When the motor 2 parameters are active the decimal point that is second from the right on the 1st row of
the display is lit. If this parameter is one when an auto-tune is carried out (Pr 5.12 = 1), the results of the auto-tune are written to the equivalent
second motor parameters instead of the normal parameters. Each time this parameter is changed the accumulator for motor thermal protection is
reset to zero.
Displays the number of the last set of defaults loaded, i.e. 1233, 1244, etc.
This parameter is used to start and stop the drive Onboard PLC program.
The drive Onboard PLC program status parameter indicates to the user the actual state of the drive Onboard PLC program. (not fitted / running /
stopped / tripped.)
