Drive Configuration Chapter 1
Configuration
Flying Start can be configured by setting P356 [FlyingStart Mode] to the
following:
• 0 “Disabled”
• 1 “Enhanced”
• 2 “Sweep”
Disabled
Disables the feature.
Enhanced
An advanced mode that performs the motor reconnect quickly by using the
motor’s CEMF as a means of detection. This mode is the typical setting for this
feature.
Sweep
The Frequency Sweep mode is used with output sine wave filters. It attempts a
reconnect by outputting a frequency starting at P520 [Max Fwd Speed]+ P524
[Overspeed Limit] and decreasing according to a slope that is modified by P359
[FS Speed Reg Ki] until there is a change in the monitored current indicating the
speed of the spinning motor has been found. If the motor was not found from the
forward sweep, the drive sweeps in the reverse direction from P521 [Max Rev
Speed]+ P524 [Overspeed Limit].
