GD310-UL series VFD
Control long vibration
If the vibration periods are longer than the set value of integral time (Ti), it is necessary to prolong the
integral time (Ti) to control the vibration for the strong integration.
Control short vibration
Short vibration period and the same set value with the derivative time (Td) mean that the derivative
time is strong. Shortening the derivative time (Td) can control the vibration. When setting the
derivative time as 0.00 (namely no derivation control) is useless to control the vibration, decrease the
gain.
