Applicable 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.

Applicable 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.

Applicable 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 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%)
