4. SAFETY OBSERVATION FUNCTION
4.4.3 Using a drive safety integrated motion controller
(1) Summary
When input devices are used, a drive safety integrated motion controller cannot be used. Using a safety
compatible motion controller brings the following characteristics.
(a) Transmitting each function command input through network
STOC (STO command), SS1C (SS1 command), SLS1C (SLS1 command), SLS2C (SLS2
command), SLS3C (SLS3 command), and SLS4C (SLS4 command) can be transmitted through
network.
(b) Feedback for each function output through network
Safety position data of servo motor with functional safety, STOS (STO output), SSMS (SSM output),
etc. can be transmitted through network.
(2) Parameter setting
Set a communication cycle for SSCNET III/H with the following parameter. Set the same value as of the
motion controller to "Safety communication - Communication cycle". When a different value is set, [AL.
7C.1 Functional safety unit communication cycle error (safety observation function)] will occur.
4.4.4 Servo motor with functional safety
Using a servo motor with functional safety enables you to use speed monitoring functions and position
monitoring functions without external encoders for duplication of encoders.
When using a servo motor with functional safety, set [Pr. PSA02 Functional safety unit setting] to "_ _ 1 _".
When not using it, set [Pr. PSA02] to "_ _ 0 _". Refer to section 4.1 for details.
