FB502 ACS_DRIVE_PZD

FB502 is used to send additional process data between the PLC and the drive.
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 FB502 (ACS_DRIVE_PZD) is not useful for those types. PPO
types 2 and 4 have 6 PZDs in each direction, so a part of FB502 (PZD3 to PZD6) is useful here. PPO
types 5 and 6 have 10 PZDs in each direction, so the full range of FB502 is useful for those types.
