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.
