Response
Time t
Control long-term vibration:
If the cycle of periodic vibration is longer than the set value of
integral time (Ti), it indicates the integral action is too strong, prolong the integral time (Ti) to
control vibration.

Time t
Response
Control short-term vibration
: If the vibration cycle is short is almost the same with the set
value of derivative time (Td), it indicates derivative action is too strong, shorten the derivative
time (Td) to control vibration. When derivative time (Td) is set to 0.00 (namely no derivative
control), and there is no way to control vibration, decrease the proportional gain.
