9-124 Compendium Motion Control SIMOVERT MASTERDRIVES
The application example contains the following configuration:
♦ 2 Siemens synchronous servo motors: 1FK6 with resolver and 1FT6
with optical sine/cosine encoder (only one motor required for
positioning)
♦ 2 MASTERDRIVES MC converters with technology option F01 (only
one converter required for positioning)
♦ Both drives should be operated in the following modes:
• Homing (this is required for positioning, since resolvers and
optical encoders are incremental and not absolute encoders)
• Point-to-point positioning (MDI; axis type "rotary axis", i.e. without
fixed stops)
• Synchronization with 1:1 transmission ratio using the virtual
master axis and the SIMOLINK drive interface
♦ When the two-axis pack is used, the synchronization can be
checked with reference to an LED light beam, which is visible
through drilled holes in the flywheel mounted on the motor shafts
when the synchronization is operating correctly.

Fig. 9-46 Application example 2: hardware configuration and wiring
The application example guides you through the relevant pages of the
function diagram and the parameter settings. It is assumed that the
basic units have been started up in speed control mode, as described
in Chapter 6. If you only want to use the positioning functions, you need
only one drive instead of two for the self-study and you can skip the
sections starting from 9.7.10.
9.7.2.2 Overview diagram
The overview diagram in Fig. 9-47 shows how the technology functions
are interconnected.
