Gain Adjustment and Machine Rigidity
The specific vibration (resonance frequency) of the mechanical system has a
large impact on the gain adjustment. The servo system responsiveness cannot
be set high for machines with a low resonance frequency (low machine rigidity).
Check the following items to increase mechanical system rigidity.
Lay the foundation firmly and set up a machine so that it does not wobble.
Use a Decelerator with minimal backlash.
Use couplings of a type with high rigidity and designed for servo systems.
Use a wide timing belt, and use a tension within the allowable axial load for the
Servomotor.
