Gain Adjustment and Machine Rigidity
The natural vibration (resonance) 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 fre-
quency (low machine rigidity).
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.
• When you use a timing belt, select a wide one. Use a tension within the range of allowable axial load
for the Servomotor or decelerator output.
• When you use gears, select ones with small backlash.
