5.21 RESET CODES: 2-WIRE, 3-WIRE INITIALIZATION

n001 : Parameter Selection / Initialization
The following table shows which parameters can be programmed (displayed & changed) or only
displayed when n001 is selected.
Setting Function
0 n001 can be read and set;
n002 - n179 read only
1 n001 - n039 can be read and set
2 n001 - n067 can be read and set
3 n001 - n113 can be read and set
4 n001 - n179 can be read and set
5 n001 - n179 can be read and set – Run Command accepted during Program Mode
6 Clear Fault Record Only
7 Not Used
10 Initialization: 2-Wire control
11 Initialization: 3-Wire control
Entering a "5" into n001 will allow a RUN command to be accepted even if the drive
is in Program mode (PRGM function LED on) or the LO/RE function LED is on. This condition
may cause the motor to run; equipment damage or personal injury may result.
By entering a "10" or an "11" into n001, all parameters in the Drive
will return to their factory settings.
Parameter Terminal
n050 S1
n051 S2
n052 S3
n053 S4
n054 S5
n055 S6
n056 S7
Know your application before using either Initialization function of n001 .
This parameter must be set to " 0 " to " 5 " for operation.
" 10 " = Factory 2-Wire Control Initialization (Maintained RUN Contact)
" 11 " = Factory 3-Wire Control Initialization (Momentary START/STOP Contact)
Entering either Initialization code resets all parameters to factory settings, and
automatically returns n001 setting to " 1 ". If the Drive is connected for 3-Wire
control and this parameter is set to " 10 " (2-Wire Control Initialization), the motor
may run in reverse direction WITHOUT A RUN COMMAND APPLIED. Equipment
damage or personal injury may result.
After " 10 " or " 11 " has been entered in n001 , the Motor Rated Current (n036 )
MUST BE REPROGRAMMED to the correct setting for the application.
