Commercial Power/ASD Switching Frequency
Program
Terminal
Line Power Switching
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 ASD and to switch to commercial power
once reaching the frequency set here.
See
F354
for additional information on this parameter.

ASD Side-Switching Delay Time
Program
Terminal
Line Power Switching
This parameter determines the amount of time that the ASD will wait before
outputting a signal to the motor once the switch-to-ASD-output criteria has
been met.
See
F354
for additional information on this parameter.

Commercial Power Side Switching Delay Time
Program
Terminal
Line Power Switching
This parameter determines the amount of time that the ASD will wait before
allowing commercial power to be applied to the motor once the switch-to-
commercial-power criteria has been met.
See
F354
for additional information on this parameter.
Direct Access Number — F357

Commercial Power Switching Freq. Hold Time
Program
Terminal
Line Power Switching
This parameter determines the amount of time that the connection to
commercial power is maintained once the switch-to-ASD-output criteria has
been met.
See
F354
for additional information on this parameter.
Direct Access Number — F358
