Goodrive300-21 integrated machine for air compressor
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.
Control short-term vibration: If the vibration cycle is as short almost the same as the set value of
differential time (Td), it indicates the differential action is too strong. Shorten the differential time (Td)
to control vibration. When the differential time (Td) is set to 0.00 (namely no differential control), and
there is no way to control vibration, decrease the proportional gain.
