6 General Parameter Set-up
6.1 Configuration
6.1.1 General Parameter Set-up
See 6.3 Parameter List to configure an operation of the safety option. The set-up is done via the MCT 10 Safe Plug-in.
Speed monitoring by the safety option
If an external encoder is connected to the safety option and selected in parameter 42-10 Measured Speed Source, speed monitoring is
active all the time whether a safety function is requested or not. However, if an STO is triggered (either directly, or as a consequence of
a Safe Stop 1) it interrupts the speed monitoring.
Encoder configuration
To define the type of feedback used by the safety option, select [1] Safe option in parameter 42-10 Measured Speed Source.
6.1.2 Configuration of Safety Functions
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, braking ramps for the safety functions, monitoring of motion sequences.
NOTICE
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.
Downloading the configuration to the safety option:
• On single-drive systems, via the RS486/USB interface on the drive.
• On networked systems, via RD485 or fieldbus interface on the MCT 10 Safe Plug-in. The control system passes the configuration to
the respective safety option.
• The feasibility of the configuration is checked when it is downloaded.
Further information on configuration and setting parameters for the safety functions is available in the online help for the MCT 10 Safe
Plug-in and in the VLT® Motion Control Tool MCT 10 Operating Guide.
The safety option is configured with the commissioning software MCT 10 Set-up Software via a Safe Plug-in. The Safe Plug-in in the
commissioning software is available as default from version 3.18.
The commissioning software provides the following menu items for the safety option:
