VBUS.DCOPERATION

Description

This parameter indicates whether the mains input is DC or AC.

If the mains input in DC and it is connected to DC+/DC- terminals (X3), not setting this parameter to 1 will cause “AC input phase loss” error.

• 
  
• If using DC mains, Kollmorgen recommends the mains input is connected to R/S/T (L1/L2/L3) terminal as opposed to DC+/DC- terminal.

• The reason is the voltage of DC+/DC- may go above the mains voltage in regenerative breaking mode, and this can damage the DC power supply feeding the drive.

Examples

Usage

If the parameter is set to 0 ->1, the drive assumes the mains input is DC, and phase loss detection as well as power loss detection are turned off.

If the parameter is set to 1 ->0, the drive assumes the mains input is AC, and depending on the status of VBUS.THREEPHASE phase loss detection may be turned on.
