VBUS.OVFTHRESH

Description

This parameter returns the DC bus overvoltage fault threshold. When the measured DC bus voltage exceeds the threshold, an overvoltage fault is thrown.

Examples

Usage

The drive configures this parameter based on power electronics component ratings. When the measured DC bus voltage VBUS.VALUE is greater than VBUS.OVFTHRESH, the drive throws Fault 2006: Bus over voltage

Code

--> VBUS.OVFTHRESH
420 [Vdc]
--> VBUS.VALUE
425.774 [Vdc]
--> DRV.FAULTS
1-2006: Bus over voltage.
2-2006: Bus over voltage.

Context

For more information on DC bus voltage protection, refer to Power View and Regeneration.
