Kinetix 5700 Safe Torque-off Function
Explicit Messages
You can use explicit messages to obtain additional diagnostic information from
the safety controller by using an MSG instruction.
Safety Supervisor State
The safety supervisor state provides information on the state of the integrated
safety connection and the mode of operation. There is only one safety
supervisor object per drive module. Therefore, for dual-axis inverters, the
safety supervisor is the same on both axes.
