Pause signal input
Urgent stop/Stop/Pause commonly use mechanical on-off, in order to avoid interfere, we
usually use
normally off contact
of mechanical on-off, according to the followed picture to
connect.
Attention
::::
System require urgent stop, start ,pause and the logic of margin is uniform, this is all
connect to normally on or normally off (in common use). After system start, it will check the
state of
start bit
automatically and as control base. So, if don’t connect external
start on-off,
the corresponding
start-bit
should be connected to
24V
ground (simple to connect to normally
off contact) or connect none(simple to connect to normally on contact).
2) Margin / origin signal input
Margin/origin usually use mechanical on-of or double thread magnet on-off and NPN, PNP
Hall on-off. Toward use mechanical on-off or double thread magnet on-off , you can connect
according to as the above item 1). If use NPN or PNP model Hall on-off, you can connect
according to the picture below.
