Safety Precautions

WARNING

Wiring
Connect this Controller correctly to the servo amplifier, encoder, and limit sensors ac-
cording to the instructions in this manual. Not doing so may cause the motor to run
away, resulting in serious accidents.
For the Power Supply Unit or any other power supply connected to peripheral devices,
connect the 0-V side to ground, or do not ground them at all.
Depending on how devices connected to the non-insulated circuit are grounded, the
power supply may be short-circuited.
Never ground the 24-V side of the power supply, as shown in the following figure.

During Power Supply
Do not attempt to take any Unit apart.
In particular, high-voltage parts are present in the Power Supply Unit while power is
supplied or immediately after power is turned OFF. Touching any of these parts may
result in electric shock. There are sharp parts inside the Unit that may cause injury.
Fail-safe Measures
Provide safety measures in external circuits to ensure safety in the system if an abnor-
mality occurs due to malfunction of the products or due to other external factors affect-
ing operation. Not doing so may result in serious accidents due to incorrect operation.
Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures
must be provided in external control circuits.
You must take fail-safe measures to ensure safety in the event of incorrect, missing, or
abnormal signals caused by broken signal lines, momentary power interruptions, or
other causes.
