240 Parameters
Enables/disables speed controller adaptation based on motor
flux reference (
.
The proportional gain of the speed controller is multiplied by a
coefficient of 0…1 between 0…100% flux reference
respectively.
See also the block diagram on page
Disable
Speed controller adaptation based on flux reference disabled. 0
Enable
Speed controller adaptation based on flux reference enabled. 1
Activates (or selects a source that activates) the speed
controller autotune function. See section
).
The autotune will automatically set parameters
,
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
) and zero speed (
) have
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.
