VBUS.OVWTHRESH

Description

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

Examples

Usage

The default value of VBUS.OVWTHRESH is 0, which turns the overvoltage warning off.

If this parameter is nonzero, the drive throws Warning 2006: Bus over voltage, when the measured DC bus voltage VBUS.VALUE is greater than VBUS.OVWTHRESH. It clears the warning when VBUS.VALUE drops below 97% of VBUS.OVWTHRESH.

Code

When VBUS.OVWTHRESH is set to 0, the drive does not report an overvoltage warning.

--> VBUS.OVWTHRESH
0 [Vdc]
--> VBUS.VALUE
403.723 [Vdc]
--> DRV.WARNINGS
No warnings active

Change the overvoltage warning level to a nonzero value. When the bus voltage is higher than this value, the overvoltage warning is reported on each axis.

--> VBUS.OVWTHRESH 400
--> VBUS.OVWTHRESH
400 [Vdc]
--> VBUS.VALUE
403.723 [Vdc]
--> DRV.WARNINGS
1-2006: Warning: Bus over voltage.
2-2006: Warning: Bus over voltage.

When the bus voltage drops below the VBUS.OVWTHRESH, but is still greater than 97% of the threshold, the warning persists.

--> VBUS.VALUE
394.272
--> DRV.WARNINGS
1-2006: Warning: Bus over voltage.
2-2006: Warning: Bus over voltage.

When the bus voltage drops below 97% of VBUS.OVWTHRESH, the warning is removed.

--> VBUS.VALUE
378.521
--> DRV.WARNINGS
No warnings active
