This is one of safety functions defined in IEC 61800-5-2.
This is the safety function that starts deceleration of the motor and executes the STO
function after a specified time has passed.
This is one of safety functions defined in IEC 61800-5-2.
This is the safety function that starts deceleration of the motor and prevents the motor
from stopping at a distance greater than the allowable deviation from the specified posi-
tion after a specified time has passed.
This is one of safety functions defined in IEC 61800-5-2.
This is the safety function that prevents the motor speed from exceeding the specified
speed.
This is one of safety functions in the Safety Module.
This is the safety function that is equivalent to the Safe Torque Off function defined in
IEC 61800-5-2.
This is one of safety functions in the Safety Module.
This is the safety function that is equivalent to the Safe Stop 1 function defined in IEC
61800-5-2.
This is one of safety functions in the Safety Module.
This is the safety function that is equivalent to the Safe Stop 2 function defined in IEC
61800-5-2.
Stopping function in the Safety Module.
This is the safety function that is equivalent to the Safely-Limited Speed function
defined in IEC 61800-5-2.
The Safety Module is shutting OFF power supply to the motor by executing the HWBB
function of SGDV SERVOPACK.
Safe state depends on safety functions used.

SLS-D function
state
The Safety Module is monitoring deceleration operation of the motor.
The Safety Module is monitoring distance that the motor moved.
The Safety Module is monitoring constant-speed operation of the motor.
Parameter related to the safety functions of the Safety Module.
These parameters contain the information related to the safety functions of SERVO-
PACKs and servomotors, and are managed by the Safety Module.
Reset the servo system by shutting OFF the power or executing software reset (Fn030).
Recalculation of parameter by CONFIG command via MECHATROLINK-II or by the
request from the Command Option Module.
Scheduled tests defined in IEC 61508-4.
This is the test that is used to detect the failure of the safety-related system.
