Programming the Replacement Drive
Replacement drives come from the factory with standard factory default parameter settings. They are not “Bypass ready” and
the parameters in the replacement Drive will need to be modified for Bypass compatibility.
Several approaches to this may be available:
1.
The digital operator/keypad from the old Drive may contain a copy of the parameter settings for this application. See
parameter o3-01 in Chapter 5 for instructions.
2. The customer may have a file of parameter settings for the PC software “DriveWizard” which can be used to download
these values to the Drive. Information and instructions for DriveWizard are available at www.drives.com.
3. Page 2 of the Bypass Schematic has a table of Drive “Factory Parameter Settings” for Bypass applications of drives. The
Bypass schematic was delivered as part of the original Bypass assembly and is re-produced in Chapter 2 of this manual.
These settings can be manually entered into the new Drive after setting the access level in parameter A1-01 to advanced
(“2: Advanced Level”).
Using one of these methods, load the Drive with the Bypass “factory default” settings and verify correct Bypass operation.
