Setting description: Speed model reference control gain
Speed reference control adjustment method
1. Please set the speed reference control parameters as the default values.
2. Please set the load inertia ratio (Cn025) correctly.If the load inertia ratio was not set correctly, it
may not be able to be controlled normally and vibrations will be generated.
3. Enable speed reference control flag (tn839.0=1). [Enabled by default]
4. Adjust servo gain (Sn211 speed control gain and Sn212 speed integral time constant).Increase the
system control gain within the range of not causing overshoot or vibrations.
5. Within the range where the system will not generate vibration or noise, use 10% as a unit to
increase the speed reference control gain (tn840). Please set the adjustment range within 200%.
※ This parameter can be adjusted through off-line tuning
