FC501 ACS_DRIVE_PZD
FC501 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 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.
1. Right-click in the next free network and choose Insert empty box.
2. Write FC501 in the block field to create an instance of FC501.
Figure 101 FC 501
3. Connect the FC501 block inputs and outputs. All block inputs and outputs need to be connected.
In the example below, the Instance Data block of FC501 ABB_DRIVE_CONTROL_FB has been
named ABB_DRIVE_CONTROL_FB_DB and an ACS355 with FPBA-01 PROFIBUS module is
been used.

types for FC501 (page 66 ).
