Commercial Power/ASD Output Switching Enable Selection
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
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
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 Trip
2 — Switch at Switching Frequency
3 — Switch at Trip and at Switching Frequency
