Description
Enables/disables speed controller adaptation based on motor
flux reference (01.24 Flux actual
The proportional gain of the speed controller is multiplied by a
coefficient of 0...1 between 0...100% flux reference
respectively.

Activates (or selects a source that activates) the speed
controller autotune function. See section
autotune (page 81).
The autotune will automatically set parameters
proportional gain, 25.03 Speed integration time
Mechanical time constant.
The prerequisites for performing the autotune routine are:
• the motor identification run (ID run) has been successfully
completed
• the speed and torque limits (parameter group
have been set
• speed feedback filtering (parameter group
selection), speed error filtering
conditioning) and zero speed
been set, and
• the drive has been started and is running in speed control
mode.
WARNING! The motor and machinery will run against
the torque and speed limits during the autotune
routine. MAKE SURE IT IS SAFE TO ACTIVATE THE
AUTOTUNE FUNCTION!
The autotune routine can be aborted by stopping the drive.
