Mpow-01 Auxiliary Power Extension Module - ABB ACS355 series User Manual

MPOW-01 auxiliary power extension module


Description
The MPOW-01 auxiliary power extension module is used in installations where the
drive's control part is required to be powered during network failures and
maintenance interruptions. The MPOW-01 provides auxiliary voltages to the control
panel, fieldbus and I/O.
Note: If you change any of the drive parameters when the drive is powered
through the MPOW-01, you have to force parameter saving with parameter
PARAM SAVE by setting the value to (1) SAVE...; otherwise all changed data
will be lost.
