Notes:

Supported safety sub-functions and their safety levels vary by the combinations of the servo amplifier or the drive unit and the servo motor, and the firmware version of the servo amplifier. Refer to "List of supported safety sub-functions".
When DI/O connection (CN8) is used, a diagnosis using test pulses is required to meet Category 4 PL e, SIL 3.
The performance of special proof tests within the mission time of the product is regarded as not necessary, however, the diagnostic interval is suggested as at least one test per three months for Category 3 PL e, SIL 3 on IEC 61800-5-2:2016.

Notes:

Supported safety sub-functions and their safety levels vary by the combinations of the servo amplifier or the drive unit and the servo motor, and the firmware version of the servo amplifier. Refer to "List of supported safety sub-functions".
When DI/O connection (CN8) is used, a diagnosis using test pulses is required to meet Category 4 PL e, SIL 3.
This value is applicable when the transmission interval monitor time is 32.0 ms or less.
Set the communication cycle as follows:
● 125 μs or more for MR-J5-G(4)-RJ and MR-J5D1-G4
● 500 μs or more for MR-J5D2-G4 and MR-J5D3-G4
The observation speed can be set separately.
The test pulse is a signal for the external circuit to perform self-diagnosis by turning off the signals to the servo amplifier or the drive unit instantaneously at regular intervals.
The listed value is applicable when the safety sub-functions through the network connection are executed.
This value is applicable when the transmission interval monitor time is 64.0 ms or less.

Notes:

Combine the servo amplifier with an R_SFCPU safety CPU with firmware version of 20 or later.
The listed safety levels are applicable when a safety CPU or a safety controller that meets Category 4 PL e, SIL 3 executes safety sub-function control. When a forced stop switch, a safety switch, or an enable switch is directly connected to the servo amplifier, the safety level is Category 3 PL d, SIL 2.
A fully closed loop system does not support SS1-r, SS2, SOS, SLS, SSM, SDI, and SLI.
The safety sub-functions are supported by MR-J5W_-G manufactured in November 2019 or later.
Set the communication cycle as follows:
● 125 μs or more for MR-J5-G(4)-RJ and MR-J5D1-G4
● 500 μs or more for MR-J5D2-G4 and MR-J5D3-G4
When DI/O connection (CN8) is used, a diagnosis using test pulses is required to meet Category 4 PL e, SIL 3.
The safety sub-functions through the network connection are not available when the servo amplifier uses CC-Link IE Field Network Basic.
The servo amplifiers support SS1-t when combined with MR-J3-D05. Refer to "MELSERVO-J5 catalog" for details.
The STO function can be set for each axis.
For 200 V class servo amplifiers, the firmware version B2 or later is required.
The functional safety unit (MR-D30) cannot be connected.
The safety sub-functions through the network connection are not available when the servo amplifier uses CC-Link IE TSN Class A.
The safety sub-functions through the network connection are not available when the servo amplifier uses driver communication function.
