Lenze TCF Series - Manual (Page 34)

The TCF 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 . The TCF drive will only work with
blue EPMs; the black EPMs will not work .
STOP!
Do NOT remove the EPM while power is applied to the drive . Damage to the
EPM and/or drive may result .
The EPM Programmer, available as an option from Lenze-AC Tech, has the ability to quickly
and easily program many TCF Series drives for the same configuration . Once a “master” EPM
is programmed with the desired parameter settings, the EPM Programmer can copy those
settings to other EPMs, allowing many drives to be configured very quickly . Consult the EPM
Programmer Instruction Manual or contact Lenze-AC Tech 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The drive will then flash “GF” to indicate that the OEM settings are no longer valid . This will
require that the EPM 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 .
