ABB ACS880 - Drive Configuration and Programming; Programming Via Parameters

Drive configuration and programming
The drive control program is divided into two parts:
• firmware program
• application program

Drive control program
The firmware program performs the main control functions, including speed and
torque control, drive logic (start/stop), I/O, feedback, communication and
protection functions. Firmware functions are configured and programmed with
parameters, and can be extended by application programming.

Programming via parameters
Parameters configure all of the standard drive operations and can be set through
• the control panel, as described in chapter Using the control panel
• the Drive Composer PC tool, as described in Drive Composer start-up and
maintenance PC tool user’s manual (3AUA0000094606 [English]), or
• the fieldbus interface, as described in chapters Fieldbus control through the
embedded fieldbus interface (EFB) and Fieldbus control through a fieldbus
adapter.
All parameter settings are stored automatically to the permanent memory of the
drive. However, if an external +24 V DC power supply is used for the drive control
unit, it is highly recommended to force a save by using parameter 96.7 before
powering down the control unit after any parameter changes have been made.
If necessary, the default parameter values can be restored by parameter 96.6.
