VBUS.THREEPHASE

Description

This parameter indicates whether the AC line input to the DC bus is single or three phase, and whether phase loss detection is active.

Examples

Usage

If the parameter is set to 0, the drive assumes that the AC line input is single phase, and phase loss detection is turned off.

If the parameter is set to 1, the drive assumes that the AC line input is three phase, and phase loss detection is turned on. If the drive detects a phase loss condition through monitoring DC bus voltage measurements, and an axis is enabled, it throws Fault 2014: AC input phase loss on each axis.

Code

--> VBUS.THREEPHASE 1
--> DRV.FAULTS
1-2014: AC input phase loss.
2-2014: AC input phase loss.


--> VBUS.THREEPHASE 0
--> DRV.FAULTS
No faults active
