Speed Control Speed Loop Switching Time at Parameter Change
(d25)
Parameters can be switched even when the inverter is operating. The parameters that can be switch-
ed include the P gain and I integral time of the speed control system. When these parameters are
switched while the inverter is operating, in some load operating conditions, sudden torque fluctuations
may occur and cause mechanical shock which may be problematic.
To alleviate this kind of shock, suppress sudden fluctuations in torque by setting the ramp function in
