Gain Adjustment Procedure
Gain Adjustment and Machine Rigidity
To improve machine rigidity:
Install the machine on a secure base so that it does not cause any play.
Use couplings that have a high rigidity, and that are designed for servo systems.
Use a wide timing belt. And use a tension within the range of allowable axial load for the motor or
Decelerator output.
Use gears with small backlash.
The specific vibration (resonance frequency) of the mechanical system has a large impact on the
gain adjustment of the servo. The servo system responsiveness cannot be set high for machines
with a low resonance frequency (low machine rigidity).
