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, torque
and frequency 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 via
• the integrated panel, as described in chapter Control panel
• an external panel
• the Drive composer PC tool, as described in Drive composer 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 96.07 Parameter save
manually before powering down the control unit after any parameter changes have
been made.
If necessary, the default parameter values can be restored by parameter 96.06
