Possible
Safety plug
Short-circuit
with a jumper
cable
Used to turn OFF the servo
power if the door on the
safeguarding is opened.
Connect to the interlock sig-
nal from the safety plug on
the safeguarding door. If the
interlock signal is input, the
servo voltage is turned ON.
As long as the signal is ON.
The servo power cannot be
turned ON. Note that these
signals are disabled in
teach mode.

Possible
External emergency stop
signal
Short-circuit
with a jumper
cable
Used to connect the emer-
gency stop switch of an ex-
ternal device.
If the signal is input, the ser-
vo power is turned OFF and
the job is stopped.
As long as the signal input is
active, the servo power can-
not be turned ON.

Used to connect a Enable
switch other than the one on
the programming pendant
when two people are teach-
ing.

Possible
Full-speed Test
Open
Used to reset the slow
speed limit for the test run in
the teach mode.
If this signal input circuit is
short-circuited, the speed of
the test run becomes 100%
in the teach mode. If this
signal’s circuit is open, the
status SSP input signal de-
termines the safety speed:
The first slow speed (16%)
or second slow speed (2%).
