Showing help for All Fieldbus and Functional Safety All

Select your Fieldbus

The model number will indicate what kind of fieldbus you have. Find the label on the side of the device, where "Model No:" is indicated. Modbus is included with all models.

Select your Functional Safety Version

The model number will indicate what kind of function safety you have. Find the label on the side of the device, where "Model No:" is indicated.

Power View

From the Power screen, you can view and configure the drive power settings as follows.

Section Element Description Parameter
Voltage VBus Gauge A graphical gauge representation of the DC bus voltage, including ranges for warnings and faults. The slider adjusts the zoom level of the gauge. VBUS.VALUE
Under Voltage Fault Threshold Sets the value at which an under voltage fault will occur

VBUS.UVFTHRESH

Under Voltage Warning Threshold Sets the value at which an under voltage warning will occur VBUS.UVWTHRESH
Actual Value Displays the current actual voltage value VBUS.VALUE
Over Voltage Warning Threshold Sets value at which an over voltage warning will occur. Setting a value of 0 generates no warning. VBUS.OVWTHRESH
Over Voltage Fault Threshold Sets value at which an over voltage fault will occur VBUS.OVFTHRESH
Under Voltage Fault Mode Sets the behavior for when an under voltage fault are monitored. VBUS.UVMODE
Input Input Mains Sets whether the mains input is DC or AC. VBUS.DCOPERATION
Nominal AC Line Sets the operating voltage of the drive. VBUS.ACNOMINAL
AC Line Phases Sets whether the AC line input to the DC bus is single or three phase, and whether phase loss detection is active. VBUS.THREEPHASE

See Regeneration for more information about regen resistors and sizing regen resistors. 

Operating Voltage

Operating voltage can be selected by the user to allow 480VAC drives to work on 240VAC input supplies.

The VBUS.ACNOMINAL parameter has an effect on the following voltage-thresholds:

  1. DC-bus over-voltage threshold (see VBUS.OVFTHRESH).
  2. The regen-resistor enable/disable voltage thresholds.
  3. The inrush-relay enable/disable voltage thresholds.

A power-cycle is needed after changing the value and saving the parameter on the NV memory of the Drive, since the voltage thresholds mentioned above are read during the boot-sequence of the drive.
