FC501 ACS_DRIVE_PZD (optional)
FC501 is used to send additional process data between the PLC and the drive. Insert a new Empty Box
to your program and name FC501 (FC501 ACS_DRIVE_PZD is included in the ABB drives library
ABB_DRIVE_LIB).

Depending on actual PPO type, a certain number of data words (PZDs) are exchanged. PPO types 1 and
3 have only 2 PZDs in each direction, so FC501 (ACS_DRIVE_PZD) is not useful for those types. PPO
types 2 and 4 have 6 PZDs in each direction, so a part of FC501 (PZD3 to PZD6) is useful here. PPO
types 5 and 6 have 10 PZDs in each direction, so the full range of FC501 is useful for those types.
Connect the FC501 block inputs and outputs. All block inputs and outputs need to be connected.
