0, drv: Drive encoder
The position feedback from the encoder connected to the drive itself is used to derive the speed feedback for the speed controller and to calculate the 
motor rotor flux position.
1, Slot1: Solutions Module in slot 1
The position feedback from the Solutions Module in Solutions Module slot 1 is used to derive the speed feedback for the speed controller and to 
calculate the motor rotor flux position. If a position feedback category Solutions Module is not installed in slot 1 the drive produces an EnC9 trip.
2, Slot2: Solutions Module in slot 2
3, Slot3: Solutions Module in slot 3
