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
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
switching frequency, resulting in the ASD-to-commercial
power switching.
Deactivation of the discrete input terminal starts the hold-time
counter setting (
) 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
