146 H9 ASD Installation and Operation Manual
Commercial Power/ASD Output Switching
Program ⇒ Terminal ⇒ Line Power Switching
This parameter Enables/Disables the Commercial Power/ASD Output
Switching function.
When enabled, the system may be set up to discontinue using the output of the
drive and to switch to the commercial power in the event that 1) a trip is
incurred, 2) a user-set frequency is reached, or 3) if initiated by a discrete input
terminal.
Once set up with the proper switching frequency and hold times, the system
will switch to commercial power upon reaching the
F355 frequency criterion.
Switching may also be accomplished manually by activating the discrete input
terminal Commercial Power ASD Switching. Terminal activation forces the
ASD output speed to accelerate to the
F355 switching frequency, resulting in
the ASD-to-commercial power switching.
Deactivation of the discrete input terminal starts the hold-time counter setting
(
F356) for ASD-to-commercial power switching. Once timed out the motor
resumes normal commercial power operation.
Settings:
0 — Off
1 — Switch at Signal Input and Trip
3 — Switch at Signal Input with Switching Frequency
4 — Switch at Signal Input and Trip with Switching Frequency
Switching Setup Requirements
F354 — Enable the switching function.
F355 — Set the switching frequency.
F356 — (speed) Hold -time before applying ASD output after the switching
criteria has been met.
F357 — (speed) Hold -time before applying commercial power after the
switching criteria has been met.
F358 — (speed) Hold -time of applying commercial power after the
switching criteria has been met.
Set a discrete input terminal to Commercial Power ASD Switching.
Set OUT1 and OUT2 to Commercial Power/ASD Switching 1 and 2,
respectively.
Note: Ensure that the switching directions are the same and that F311
is set to Permit All.
Note: The OUT1 and OUT2 outputs assigned to Commercial Power/
ASD Switching Output are used to actuate the re-routing
contactors.
