Technical Note 0 9 4
Accessing ACH550 parameters on a failed drive
Understanding the previous configuration
In this Technical Note 094 there is an outline of materials and steps to be taken to retrieve the changed parameters as
well as the I/O configuration on an existing installation of a ACH550 drive that has failed and can no longer be powered
to provide this data. The ability to retrieve this data will provide a more simplified approach to replacement of an
existing ACH550 drive when the parameters have not been backed up to the drive panel or been previously extracted
and stored for the installation.
In each method to gather the parameters from the existing installation it requires removing the existing ACH550 control
board from the non-working unit. That control board has an interface board mounted to it, along with a 24-volt DC
power supply to provide power to both boards. In this configuration, the Technician has the option of using an ACH550
control panel as the interface to display the parameters for recording or backup the parameters to that control panel.
The Technician can also use a DB9 to RJ45 Connector, USB to 232 Connector, and computer with Drive Windows Light to
view changed parameters, I/O settings, and/or create a backup of the programming on that board.
