    Is it possible to operate a Lexium 32 servo drive from single phase mains if the drive is designed for 3 phase mains?

    It is not recommended, nor is it advisable to operate a LXM32 servo drive from single phase mains if the drive is of the 3 phase desgn.

    The power will be reduced to about one third because only 1 phase mains is applied instead of three phase. 
    Also, the DC bus voltage will much lower resulting in approximately half the needed DC bus voltage.

    Additional concerns would be but very fast charge and discharge of the capacitors with 230V single phase supply could significantly reduce capacitor lifetime. 



    The parameter for disabling mains detection was intended for short term operational testing when 3 phase power is not available, as commonly available in an office environment. 
    Also, disabling of mains detection is for applications which use common DC bus. 

    In summary, no validation exists for Lexium 32 drives designed for 3 phase mains to be used on single phase mains.
