FC500 ACS_DRIVE_PARA (optional)
FC500 is used to read/write extra parameters between the PLC and the drive. Insert a new
Empty Box
to your program and name it FC500 (FC500
ACS_DRIVE_PARA
is included in the ABB drives library
ABB_DRIVE_LIB
).
Figure 46 PLC logic - FC500
Connect the FC500 block inputs and outputs. All block inputs and outputs need to be connected.
Block variables and data types for FC500
Block variable
Data type
Comment
ADR_IN
INT
The beginning of the address range of the drive's:
Parameter Identification
input for DP-V0.
Process Data
input (or 0 “zero”) for DP-V1 (or PROFINET).
ADR_OUT
INT
The beginning of the address range of the drive's:
Parameter Identification
output for DP-V0.
Process Data
output (or 0 “zero”) for DP-V1 (or PROFINET).
READ
BOOL
Read the parameter value 0
→ 1 (executed on positive edge).
WRITE
BOOL
Write the parameter value 0
→ 1 (executed on positive edge).
PARAM_NUM
DINT
Read/written parameter: 3 numbers = group, 2 numbers = Index.
For example, Par 20.06 = 2006.
VALUE_IN
DINT
Parameter value to be written.
Note:
For writing negative values to the drive, user has to input the
values in hexa decimal format in SIMATIC Manager only.
For example, -1 = DW#16#FFFFFFFFFFFFFFFF
DRIVE
BLOCK_DB Instance Data Block. The drive variable is used for identifying to
which drive FC501
ACS_DRIVE_PZD
belongs. The Instance Data
Block of FB500
ABB_DRIVE_CONTROL_FB
must correspond to
the variable FC501 ACS_DRIVE_PZD drive of the same drive.
DONE
BOOL
FALSE=Block execution not finished, TRUE=Block execution
finished.
ERR
BOOL
FALSE=No error, TRUE=Error occurred during block execution.
ERNO
WORD
Error code when ERR=TRUE.
