BusOvervoltageThreshold Parameter
Default Value: 0
Minimum Value: 0
Maximum Value: None
Units: volts
Type: float
IMPORTANT: This parameter applies only to PWM drives. This parameter does not apply when used with linear, piezo, or interface drives.
The BusOvervoltageThreshold parameter limits the bus voltage of a drive when set. If the bus voltage is more than the value specified by the BusOvervoltageThreshold parameter, a BusOvervoltageFault is triggered. When the BusOvervoltageThreshold parameter is set to 0, the parameter is disabled.
The hardware also checks the bus voltage and triggers a BusOvervoltageFault if the bus voltage gets to a dangerous level. The BusOvervoltageThreshold parameter has no effect on this hardware signal, and the two trigger the BusOvervoltageFault independently from each other. The Bus Overvoltage bit of the Amplifier Status item tracks the state of the hardware bus overvoltage signal.
This parameter is set to a safe value in Machine Setup for PWM drives. The values include:
- iXA4 and XA4: 400 V
- iXC2, XC2, iXC2e, and XC2e: 100 V
- iXC4, XC4, iXC4e, and XC4e: 400 V
- iXC6e and XC6e
- (-240V): 400 V
- (-480V): 900 V
- iXR3 and XR3 (with XSP amp)
- VB1 - VB5 and VB7: 200 V
- VB6 and VB8: 400 V
