Commercial Power/ASD Switching Output
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 ASD and to switch to the commercial power if 1)
a trip is incurred, 2) a user-set ASD 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. Termi-
nal 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
2 — Switch at Signal Input with Switching Frequency
3 — 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 Switch-
ing.
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.
