Safety Precautions for Using the Safety Module

Carefully read the following important precautions and observe them when using the Safety Module.
5-2
• Installation, disassembly, or repair must be performed only by authorized personnel.
Failure to observe this precaution may result in electric shock or injury.
• Engineers designing a mechanical system using the safety functions of the Safety Module must
have complete knowledge of the relative safety standards and a full understanding of the safety
functions of the Safety Module.
Improper use may result in injury or damage to the product.
• When creating a safety design for a mechanical system using the safety functions of the Safety
Module, always perform risk assessment of the system to identify residual risks.
Improper use may result in injury or damage to the product.
• The dynamic brake is not a safety-related part of a control system. Create the safety design of the
mechanical system in such a way that any trouble in the dynamic brake function does not create a
hazard when the safety functions of the Safety Module operate.
Improper use may result in injury or damage to the product.
• Connect device conforming to the relative safety standards to the connector for Safety Request
Input Signals.
Improper use may result in injury or damage to the product.
• The safety functions of the Safety Module are not for emergency stopping. To use the safety func-
tions for emergency stopping, separately shut OFF the power supply from the electromechanical
section to the motor.
Improper use may result in injury or damage to the product.
• The safety functions of the Safety Module are not for shutting OFF the power supply to the SERVO-
PACK and do not provide electrical isolation. Be sure to separately shut OFF the power supply to
the SERVOPACK when performing maintenance or inspection of the SERVOPACK.
Failure to observe this warning may result in electric shock.
• Be sure to check the safety-related parameters before using the safety functions of the Safety Mod-
ule.
Improper use may result in injury or damage to the product.
• If the Safety Module or SERVOPACK is changed when starting the servo system or during mainte-
nance or inspection, be sure to check the operation of the safety functions in the actual application
after performing wiring.
Improper use may result in injury or damage to the product.
• Make sure that the safety function jumper connector is not connected to the connector (CN8) of the
SERVOPACK.
If the safety jumper connector is connected, the safety functions may not operate properly, which may result
in injury or damage to the product.
