External Emergency Stop Short-circuit
with a jumper
cable
Used to connect the emergency stop
switch of an external device.
If the signal is input, the servo power is
turned OFF and the job is stopped.
While the signal is input, the servo
power cannot be turned ON.

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 signal from the
safety plug on the safeguarding door. If
the interlock signal is input, the servo
power turns OFF. While the signal is
turned ON. The servo power cannot be
turned ON. Note that these signals are
disabled in teach mode.

Maintenance Input Open
If the signal input circuit is short-cir-
cuited, the Enable switch (DSW) and the
Safety Plug are disabled.
Usually, use the system with this signal
circuit open (nothing connected).
If the circuit for this signal must be used
for an unavoidable reason, be sure to
use a switch with a key that is

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-cir-
cuited, the speed of the test run
becomes 100% in the teach mode.
If this signal’s circuit is open, the status
SSP input signal determines the safety
speed: The first slow speed (16%) or
second slow speed (2%).

− Slow Speed Mode Selection Short-circuit
with a jumper
cable
Used to determine the speed of the test
run when the FST (full-speed test) signal
input circuit is open.
Open: Second slow speed (2%)
Short-circuit: First slow speed (16%)
