Example Applications
Example 1
see STEP 7 example application FMSTSVEX\EXAMPLE1
The following blocks are required, in addition to the technology functions, in
order to run this example application:
The following operating modes are supported in example 1:
The associated data (velocity levels, MDI block, single functions) are
transferred automatically to the FM after Power On or when the CPU
switches from STOP to RUN. These values can be transferred again by
setting the appropriate write memory (M17.4 to M17.6).
OB 100 contains certain default settings for velocity levels, MDI block,
single functions (servo enable, simulation), operating mode (Jogging mode is
active on start), mode parameters and override; however these can be
changed according to the application.
