98 Application macros

Modbus configuration macro
This macro configures the drive communication and control parameters. The macro is
available in ACS320 drives with firmware version 4.03c or later.
To enable the macro, set the value of parameter 9902 APPLIC MACRO to 21 (AC500
MODBUS).
The AC500 MODBUS application macro default values for the drive parameters
correspond to the ABB standard macro (parameter
9902 , value 1 (HVAC DEFAULT),
see section HVAC default on page 83 ), with the following differences:
Note : The default slave address of the drive is 2 (parameter 5303 EFB STATION ID ),
but if several drives are used, the address must be unique for each drive.
Parameters changed relative to HVAC default
