The auxiliary voltage is too low, e.g. short dip, while the drive is
in operation.
To reset, cycle the auxiliary power of the drive.
Check:
− The auxiliary voltage itself.
− The internal auxiliary voltages on the SDCS-CON-H01.
− If the problem persist, change SDCS-CON-H01 and/or
SDCS-PIN-H01 or SDCS-POW-H01 respectively.
