Start with speed capture
This mode is used after transient power fault in applications with a large inertia
load. The frequency converter firstly identifies the rotation speed and direction
of the motor, and then starts with the current frequency of the motor to realize
smooth starting without shock to the rotating motor.
Fig. 12-27: Start with speed capture
When the frequency converter is starting and accelerating, if 'Setting
frequency' is lower than [E0.36] 'Start frequency', the frequency
converter firstly starts at 'Start frequency' and runs for [E0.37] 'Start
frequency holding time', and then decelerates to 'Setting frequency'.
