Ensure that the following condition does not last longer than 5 minutes. Otherwise the
product life may be shortened.
• The ambient temperature is high, and,
• There is a high ratio of CN11 input signal contacts that are ON (closed)

∗1. The state that a contact is ON (closed) indicates, regardless of the logic of the
input signal, that the contact is closed and that current is flowing in the input
circuit.
∗2. For example, a contact ON ratio of 100% indicates that 11 out of the 11 con-
tacts are ON.
Name
Servo Alarm:
Turns OFF when an error is detected.
Error/Warning:
ON for 2 seconds when an error has occurred.
ON continuously while a warning is being detected.
Brake interlock (controls the brake):
ON when the brake is released.
Servo Ready:
ON when the control and main circuit power supplies are
ON and a Servo Alarm has not occurred.
By connecting the shielded wire of the I/O signal cable to
the connector shell, it will be connected to the frame
ground (earth).
