The SCL/SCM Series drive contains two or three sets of parameter values, depending on whether the
drive has been programmed with optional OEM default settings. The first set of values is the factory
default settings, which are permanently stored on the main control board and cannot be changed.
The second set of values is the user settings, which are stored in the EPM. When the drive leaves the
factory, the user settings are the same as the factory default settings, but the user settings can be
changed to configure the drive for a particular application. The optional third set of values is the OEM
default settings, which are also stored in the EPM. OEM default settings are typically used in cases
where many drives are used for the same application, which requires that all of the drives have the
same parameter settings. The OEM default settings cannot be changed without the optional EPM
Programmer. The drive can be programmed to operate according to the user settings or the OEM
default settings (Refer to Parameter 48 in Section 4.4).
NOTE
The drive will not operate without the EPM installed. The drive will display “F1” if the
EPM is missing or damaged.
STOP!
Do not remove the EPM while power is applied to the drive. Damage to the EPM and/
or drive may result.
The optional EPM Programmer has the ability to quickly and easily program many SC Series drives
for the same configuration. Once a “master” EPM is programmed with the desired parameter
settings, the EPM Programmer can then copy those settings to other EPMs, allowing many drives to
be configured very quickly. Consult the EPM Programmer Instruction Manual or contact the factory
for more information.
If the OEM settings in the EPM become corrupted, the drive will operate normally, until an attempt is
made to perform a RESET OEM using Parameter 48, PROGRAM SELECTION. The drive will then flash
“GF” to indicate that the OEM settings are no longer valid. The EPM must then be re-programmed
using the optional EPM Programmer.
If the OEM settings and the user settings are both corrupted, the drive will display “GF” immediately
and the drive will require a RESET 60 or RESET 50 using Parameter 48, PROGRAM SELECTION. Once
the RESET is performed, the parameters can then be programmed individually to match the OEM
default settings. This will allow the drive to operate as if it were in OEM mode, even though it is
actually operating in USER mode. Refer to Parameter 48 in Section 4.4, Description of Parameters.
NOTE
The drive will also display “GF” if a RESET OEM or OPERATE WITH OEM SETTINGS is attempted
when the EPM does not contain OEM defaults.
