6.7.1.1 Safety Functions Configuration
Safety-related parameters must be configured via a PC with MCT 10 tool and can also be copied between drives with the LCP or a
memory module.
Use the MCT 10 Set-up Software Safe Plug-in to configure the safety functions and to enable the PROFIsafe communication. The
safety functions to be carried out by the safety option are defined in the MCT 10 safe plug-in:
• Configurations of the safety functions.
• Setting of limit values for the safety functions.
Always perform the required commissioning test. The commissioning test report is automatically generated via the Safe Plug-in
in MCT 10 after downloading the parameters to the safety option.
