F355
Power Switching Frequency
Program  Special Controls
When enabled at F354 and with a properly configured discrete output terminal,
this parameter sets the frequency at which the At Frequency Powerline
Switching function engages.
The At Frequency Powerline Switching function commands the system to
discontinue using the output of the drive and to switch to commercial power once
reaching the frequency set at this parameter.
See parameter F354 for more information on this setting.
ASD Switching Wait Time
Program  Special Controls
This parameter determines the amount of time that the drive will wait before
outputting a signal to the motor once the switch-to-drive-output criteria has been
met.
See parameter F354 for more information on this setting.
Commercial Power Switching Wait Time
Program  Special Controls
This parameter determines the amount of time that the drive will wait before
allowing commercial power to be applied to the motor once the switch-to-
commercial-power criteria has been met.
See parameter F354 for more information on this setting.
Commercial Power Switching Freq. Hold Time
Program  Special Controls
This parameter determines the amount of time that the connection to commercial
power is maintained once the switch-to-drive-output criteria has been met.
See parameter F354 for more information on this setting.
PID Control Switching
Program  Feedback Settings
This parameter Enables/Disables PID feedback control.
Selecting Process PID uses the upper and lower-limit settings of parameters
and F368.
Selecting Speed PID uses the upper and lower-limit settings of parameters
and F371.
Settings:
0 — PID Off
1 — Process PID
2 — Speed PID
