Zero position of the joystick
The function supervises a
ZERO POSition PTR input in case of a stop or a
trip. The input can be used either as a NO contact or as an NC contact depending on
the configuration selected in the pointer value. The drive will check for a 1 -> 0 edge
of this input before it activates the next start. The input must be zero for the Start
command to be executed. If the drive does not accept the Start command because
there is a sequence problem in the zero position input, it generates a ZERO POS
WARN warning.
The following figure shows a connection diagram of the Zero position input for an NC
configuration.
You can also use the Zero position input for a joystick error check when the
reference is taken from a joystick. If the Zero position input is true, and the speed
reference or torque reference is greater than +/- 10% of the minimum or maximum
scaled value of the used joystick reference, a JOYSTICK CHECK warning is
generated after a delay of
JOYSTICK WARN TD. If Start commands in both
directions are true simultaneously, then it is also detected as a joystick hardware
error.
