Function
This is a unique execution signal for zero return commands stored by
command 53h.
The Ack signal responds to this signal.
* If the zero-sensor (SDN) type zero-return start function is used, pin
9 will be the zero-sensor input. Follow the instructions below to
allocate the zero-sensor signal function using command 16h. Set
command 14h, DAT4, Bit7 (SDN) = 0.
a) If H. Limit and zero-sensor are shared, set the H. Limit function of the
desired direction.
b) If only the zero-sensor function is used, set the generic input port
function.
c) To use the zero-sensor (SDN) type zero-return function, set the
desired function.
It will be the hard limit signal input for each direction.
After the limit input, the system performs a deceleration stop and the stop
position becomes the target position. During the limit period, commands
for the limit direction are disabled, but commands for the opposite limit
direction are accepted.
* The limit input is disabled during zero-return movement.
* The limit direction is defined by the positive direction setting of
command 12h.
* Only NPN output-type limit sensors are supported.
