54 Standard programposi features
Speed control mode
The motor follows a speed reference given to the drive. This mode is used either with
estimated speed used as feedback, or with an encoder or resolver for better speed
control accuracy.
Speed control mode is available in both local and external control. It is also available
both in DTC (Direct Torque Control) and scalar motor control modes.
Frequency control mode
The motor follows a frequency reference given to the drive. Frequency control is only
available for scalar motor control.
Drive configuration and programming
The drive control program is divided into two parts:
• Application program and
• Firmware program.
The firmware program performs the main control functions, including speed 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 through parameters
Parameters configure all standard drive operations and can be set through
• 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
