Drive configuration and programming
The drive control program performs the main control functions, including speed,
torque and frequency control, drive logic (start/stop), I/O, feedback, communication
and protection functions. Control program functions are configured and programmed
with parameters.
Configuring via parameters
Parameters configure all of the standard drive operations and can be set via
• the control panel, as described in chapter
• the Drive composer PC tool, as described in
Drive composer user’s manual
(3AUA0000094606 [English]), or
• the fieldbus interface, as described in chapters
embedded fieldbus interface (EFB)
and
Fieldbus control through a fieldbus
All parameter settings are stored automatically to the permanent memory of the drive.
However, if an ex24 V DC power supply is used for the drive control unit, it is
highly recommended to force a save by using parameter
before powering down the control unit after any parameter changes have
been made.
If necessary, the default parameter values can be restored by parameter
.
