Table 9-2 Key to parameter table coding
9.1 Parameter ranges and variable maximums
Some parameters in the drive have a variable range with a variable minimum and a variable maximum value which is dependent on one of the
following:
• The settings of other parameters
• The drive rating
• The drive mode
• Combination of any of the above
The tables below give the definition of variable minimum/maximum and the maximum range of these.
Coding Attribute
RW Read/Write: can be written by the user
RO Read only: can only be read by the user
Bit 1 bit parameter. ‘On’ or ‘Off’ on the display
Num Number: can be uni-polar or bi-polar
Txt Text: the parameter uses text strings instead of numbers.
Bin Binary parameter
IP IP Address parameter
Mac Mac Address parameter
Date Date parameter
Time Time parameter
Chr Character parameter
FI
Filtered: some parameters which can have rapidly changing values are filtered when displayed on the drive keypad for easy
viewing.
DE Destination: This parameter selects the destination of an input or logic function.
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 be transferred to the destination drive by non-volatile storage media when the
rating of the destination drive is different from the source drive and the file is a parameter file. However, the values will be
transferred if only the current rating is different and the file is a difference from default type file.
ND No default: The parameter is not modified when defaults are loaded
NC Not copied: not transferred to or from non-volatile media during copying.
PT Protected: cannot be used as a destination.
US User save: parameter saved in drive EEPROM when the user initiates a parameter save.
PS Power-down save: parameter automatically saved in drive EEPROM when the under volts (UV) state occurs.
VM_AC_VOLTAGE Range applied to parameters showing AC voltage
Units V
Range of [MIN] 0
Range of [MAX] 0 to 930
Definition
VM_AC_VOLTAGE[MAX] is drive voltage rating dependent. See Table 9-3.
VM_AC_VOLTAGE[MIN] = 0
VM_AC_VOLTAGE_SET Range applied to the AC voltage set-up parameters
Units V
Range of [MIN] 0
Range of [MAX] 0 to 690
Definition
VM_AC_VOLTAGE_SET[MAX] is drive voltage rating dependent. See Table 9-3.
VM_AC_VOLTAGE_SET[MIN] = 0
VM_DC_VOLTAGE Range applied to parameters showing DC voltage
Units V
Range of [MIN] 0
Range of [MAX] 0 to 1190
Definition
VM_DC_VOLTAGE[MAX] is the full scale DC bus voltage feedback (over voltage trip level) for the drive. This level is
drive voltage rating dependent. See Table 9-3.
VM_DC_VOLTAGE[MIN] = 0
