27 SM01P
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 15).
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The drive will then flash “GF” to indicate that the OEM settings are no longer valid.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 15, 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.
