2.3.8.8 Auto tuning
The results of the auto-tuning are effective in the following operating modes:
•
In closed-loop operation
• In open-loop operation with encoder
Auto-tuning is a process during which the closed-loop parameters for position and velocity controllers
are automatically adjusted. The process can be completed statically (when the motor is at a standstill)
or dynamically (when the motor is running). The dynamic process is suitable for drive systems for
which the properties are not known. The calculation is based on the following data:
–
Current regulator, which is already designed
– Suitable start parameters for position and velocity controllers
– Amplitude of excitation signal
Servo drive start values
The standard values for the position controller and speed controller are determined in this parameter
group. The start parameters are determined automatically on the basis of the drive configuration.

Results
The auto-tuning results are displayed in this parameter group once the values have been adopted by
the assistant.

Measurement of movement (identification) and Test movement (validation)
The properties for the movement measurement and movement test are defined by a test run in these
parameter groups.
The following parameters are initially not synchronised with the corresponding acceleration and decel-
eration parameters.
–
Measurement of movement (identification)
–
Maximum acceleration during the identification
– Maximum deceleration during the identification
– Test movement (validation)
–
Maximum acceleration during validation movement
– Maximum deceleration during validation movement
This ensures that different values can be specified for the acceleration and deceleration. A synchron-
isation is not carried out until the function is started in the assistant.

Start auto tuning...
Via the button "Start auto tuning...", the assistant for configuration and execution of the auto-tuning
is displayed. The button is only active if the following prerequisites are met:
–
The plug-in is connected to the device.
– The plug-in has the master control.
– Controller enable is activated.
