Manual Tuning - Siemens SIMOTICS S-1FL6 Operating Instructions Manual

Note
The real-time auto tuning may not be performed properly if the following conditions are not
satisfied:
• Accelerate the motor for 100 ms or more with the acceleration torque.
• The acceleration/deceleration torque is 15% or more of the rated torque.
Under operating conditions that impose sudden disturbance torque during
acceleration/deceleration or on a machine that its rigidity is poor, auto tuning may not
function properly, either. In such cases, use the one-button auto tuning or manual tuning to
optimize the drive.

Manual tuning

When the auto tuning cannot reach expected tuning results, you can disable the auto tuning
function by setting the parameter p29021 and manually perform tuning:
● p29021=5: auto tuning function is disabled and all control parameters are reset to tuning
default values.
● p29021=0: auto tuning function is disabled without changing control parameters.
