CAUTION
Know your application before using either Initialization function of n01 .
This parameter must be set to " 0 " or " 1 " 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 n01 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.
IMPORTANT
After " 10 " or " 11 " has been entered in
n01
, the Motor Rated Current (
n32
)
MUST BE REPROGRAMMED to the correct setting for the application.
