Terminal 28 and Interface Common
(This signal must be maintained as True to permit the drive
to operate from any control source.)
Auxiliary
Maintained True = Auxiliary Interlocks Are Closed
False = Auxiliary Interlocks Are Open
Auxiliary allows the drive to be interlocked using external interlocks. The
interlocks must be closed and this input True to permit the drive to operate.
When an interlock opens and the input is False for 90mS or longer, the
drive will initiate a programmed stop sequence and generate Fault F02.
Terminal 30 and Interface Common

the motor. If this input is False for 20mS or longer, drive operating
capabilities are not permitted and drive outputs are disabled forcing the
motor to coast-to-stop. Power however, is not be removed from the drive’s
control logic and drive programming can still be accessed.
