Set Values
Value Description
0 Displays and sets n001. Parameters from n002 to n179 can be displayed
only.
1 Sets or monitors parameters n001 through n049 (i.e., function group 1
settings).
2 Sets or monitors parameters n001 through n079 (i.e., function groups 1 and 2
settings).
3 Sets or monitors parameters n001 through n119 (i.e., function groups 1
through 3 settings).
4 Sets or monitors parameters n001 through n179 (i.e., function groups 1
through 4 settings).
5 Same operation as set to 4, but RUN command is accepted in program
mode.
6 Clears the error log.
8 Initializes parameters to default settings in 2-wire sequence. (See note.)
9 Initializes parameters in 3-wire sequence. (See note.)
10 For the USA, inizializes parameters in 2--wire sequence (See note)
11 For the USA, inizializes parameters in 3--wire sequence (See note)
Note The set value in n002 is not initialized with n001 set to 8,9,10 or 11..
Each of the following parameters is initialized according to the preset control
mode. The default value varies with the control mode. For details, refer to page
5-3.
n014 (middle output frequency), n015 (middle output frequency voltage), n016
(minimum output frequency), n017 (minimum output frequency voltage), n104
(torque compensation primary-delay time constant), n111 (slip compensation
gain), n112 (slip compensation primary-delay time constant)

·These two modes have the following characteristics.
Vector Control Mode
The Inverter in vector control mode calculates the vector of the operating condition of
the motor. Then the 150% rated output torque of the motor isprovided atan outputfre-

makes it possible to suppress speed fluctuation regardless of changes in loads. Nor-
mally set the Inverter to this mode.
