5.4 Advanced Autotuning by Reference (Fn202)
Adjustments with advanced autotuning by reference are described below.
Advanced autotuning by reference starts adjustments based on the set speed loop gain (Pn100).
Therefore, precise adjustments cannot be made if there is vibration when starting adjustments. In
this case, make adjustments after lowering the speed loop gain (Pn100) until vibration is
eliminated.
5.4.1 Advanced Autotuning by Reference
Advanced autotuning by reference is used to automatically achieve optimum tuning of the DRIVER
in response to the user reference inputs from the PC or PLC...etc.
Advanced autotuning by reference is performed generally to fine-tune the DRIVER after advanced
autotuning of the DRIVER has been performed.
If the moment of inertia ratio is correctly set to Pn103, advanced autotuning by reference can be
performed without performing advanced autotuning.
DRIVER
Advanced autotuning by reference performs the following adjustments.
• Gains (e.g., position loop gain and speed loop gain)
• Filters (torque reference filter and notch filter)
• Friction compensation
• Anti-resonance control
• Vibration suppression
Refer to
5.4.3 Related Parameters
for parameters used for adjustments.
CAUTION
・
Because advanced autotuning by reference adjusts the DRIVER during automatic operation, vibra- tion or overshooting
may occur. To ensure safety, perform advanced autotuning by reference in a state where the DRIVER can come to an
emergency stop at any time.
