Note 1: The specifications of the robot controller. When constructing systems such as safety programmable
controller programs and settings, and safety I/O devices, adopt a safe design and evaluate the safety.
Note 2: To use this product at a performance level of SIL 3, Category 4, PL e, refer to "4.6.1 Test pulse diagnosis
(EMG)".
* This table shows the specifications of robot controllers.
* Connect the robot controller's emergency stop input, door switch input, and enabling device input as described
in the Standard Specifications Manual.
* The safety communication function cannot be used together with the robot safety option (4F-SF003-05).
* For information on network specifications such as the maximum number of connectable devices per network,
refer to the following manuals.
□ MELSEC iQ-R CC-Link IE TSN User's Manual (Startup) (SH-082127ENG)
□ MELSEC iQ-R CC-Link IE TSN User's Manual (Application) (SH-082129ENG)
* For information on transmission delay times, safety response times, and safe stopping distances, refer to the
following sections.
