To improve machine rigidity:
• Install the machine on a secure base so that it does not have 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 frequencies) of mechanical systems 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).
