15.10 External emergency stop
This signal is 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.
DANGER due to electric current!
Injuries and machine damage as a result of short circuiting
Jumpers are installed at the factory. If the jumpers are not removed, the external emergency
stop will not work even when the signal is received.
Always remove the jumpers before operation.
15.11 Connection for SERVO-ON enable input
DANGER due to electric current!
Injuries and machine damage as a result of short circuiting
Jumpers are installed at the factory. If the jumpers are not removed, the external emergency
stop will not work even when the signal is received.
Always remove the jumpers before operation.
Connect the ONEN signal lines to enable the function to turn ON or OFF the SERVO power
supply of an individual SERVO when a robotic system is divided into SERVO systems.
Because these signals are not used for units of standard specifications, a jumper cable is
connected as shown in the following figure.
For safety reasons, dual circuits are used for the SERVO-ON Enable input signals. Connect
the signal so that both input signals are turned ON or OFF at the same time. If only one
signal is turned ON, an alarm occurs.
