Coding Attribute
Bit 1 bit parameter
SP Spare: not used
FI
Filtered: some parameters which can have rapidly changing
values are filtered when displayed on the drive keypad for
easy viewing.
DE
Destination: indicates that this parameter can be a
destination parameter.
Txt Text: the parameter uses text strings instead of numbers.
VM Variable maximum: the maximum of this parameter can vary.
DP
Decimal place: indicates the number of decimal places used
by this parameter.
ND
No default: when defaults are loaded (except when the drive
is manufactured or on EEPROM failure) this parameter is not
modified.
RA
Rating dependent: this parameter is likely to have different
values and ranges with drives of different voltage and current
ratings. Parameters with this attribute will not be transferred
to the destination drive by SMARTCARDs when the rating of
the destination drive is different from the source drive and the
file is a parameter file.
NC
Not copied: not transferred to or from SMARTCARDs during
copying.
NV Not visible: not visible on the keypad.
PT Protected: cannot be used as a destination.
US
User save: saved in drive EEPROM when the user initiates a
parameter save.
RW Read/write: can be written by the user.
BU
Bit default one/unsigned: Bit parameters with this flag set to
one have a default of one (all other bit parameters have a
default of zero. Non-bit parameters are unipolar if this flag is
one.
PS
Power-down save: parameter automatically saved in drive
EEPROM when the under volts (UV) trip occurs. Power-
down save parameters are also saved in the drive when the
user initiates a parameter save.
