4. Wiring and Connection
The wiring and electrical specifications of CN21/CN22 are same regardless of the Safety Module models.
Refer to manual of the Safety Module.
In addition, when using HWBB function of the CN8□, refer to SERVOPACK’s manual about HWBB function.
5. Precautions and Basic Settings Required before Starting Operation
Check the operation of the safety functions with reference to a list shown below.

5.1. Checking the Operation
When starting the system or replacing a SERVOPACK for maintenance or inspection purposes, make sure that the
relevant External Device Monitor Output Signal turns ON when the redundant Safety Request Input Signals turn OFF.
Failure of the safety functions can be detected by monitoring the Safety Request Input Signals and the External
Device Monitor Output Signals.
The following table shows the logic for the Safety Request Input Signals and the External Device Monitor Output
Signals.

Note :
1. EDM1 signal output is in unstable condition right after control power for SERVOPACK turns ON (Max. 10 seconds).
Execute checking above after 10 seconds passed after control power turns ON.
2. Input both Safety Request Input A and Safety Request Input B as ON “No Safety Function activates”.
When Safety Request Input Signal A or Safety Request Input Signal B is activated (Safe (HWBB) state), the EDM1 shows
“ON” regardless of the condition of HWBB input signal.
