Starting Methods
The methods below can be used when the drive has the following default configurations from DSE 890
installed: Closed Loop Vector, Sensorless Vector, Shaftless Printing, Shipping, Volts/Hertz.
IMPORTANT DRIVE ENABLE must be True in all cases.
Single Wire Logic Starting
Use just DIGITAL INPUT 2 when the motor direction will always be the same. The motor will run while
the RUN switch is closed, and will stop when it is open.
Note that the SETUP::SEQ & REF::SEQUENCING LOGIC::NOT STOP parameter is active (FALSE - not
wired to), meaning that the drive will only run while the RUN parameter is held TRUE.
