Parameters 183
23.20 PI tune mode Activates the speed controller autotune function.
The autotune will automatically set parameters 23.01
Proport gain and 23.02 Integration time, as well as 01.31
Mech time const. If the User autotune mode is chosen, also
23.07 Speed err Ftime is automatically set.
The status of the autotune routine is shown by parameter
06.03 Speed ctrl stat.
WARNING! The motor will reach the torque and
current limits during the autotune routine. ENSURE
THAT IT IS SAFE TO RUN THE MOTOR BEFORE
PERFORMING THE AUTOTUNE ROUTINE!
Notes:
• Before using the autotune function, the following
parameters should be set:
• All parameters adjusted during the start-up as
described in the ACQ810-04 drive modules Start-up
Guide
• 19.01 Speed scaling
• 19.03 MotorSpeed filt
• 19.06 Zero speed limit
• Speed reference ramp settings in group 22 Speed ref
ramp
• 23.07 Speed err Ftime.
• The drive must be in local control mode and stopped
before an autotune is requested.
• After requesting an autotune with this parameter, start the
drive within 20 seconds.
• Wait until the autotune routine is completed (this
parameter has reverted to the value Done). The routine
can be aborted by stopping the drive.
• Check the values of the parameters set by the autotune
function.

Done No tuning has been requested (normal operation) 0
Smooth Request speed controller autotune with preset settings for
smooth operation.
1
Middle Request speed controller autotune with preset settings for
medium-tight operation.
2
Tight Request speed controller autotune with preset settings for
tight operation.
3
User Request speed controller autotune with the settings defined
by parameters 23.21 Tune bandwidth and 23.22 Tune
damping.
4
23.21 Tune bandwidth Speed controller bandwidth after autotune procedure in user
mode. A larger bandwidth results in more restricted speed
controller settings.
0.00 … 2000.00 Hz Tune bandwidth for user PI tune mode. 100 = 1 Hz
23.22 Tune damping Speed controller damping after autotune procedure in user
mode. Higher damping results in safer and smoother
operation.
0.0 … 200.0 Speed controller damping for user PI tune mode. 10 = 1
