Function: FastMAC commands are also sometimes referred to as FlexMAC commands.
The advantage of these commands is a very low communication overhead.
FastMAC/FlexMAC commands are described in detail in section 4.5.7 of the
MAC user manual, JVL publication no. LB0047-20GB (V2.0 or newer).
However, a brief summary is in order.
If 'Mode' is set to 'Passive', 'Velocity', or 'Position', the motor will switch to
that mode. Also, one of the passive motor registers will be activated, in the
sense that its value will be written to the corresponding active motor register,
which actually controls motor behaviour. In the example above, the value in
register no. 65 (V1) will be written to register no. 5 (V_SOLL). Move
operations will then take place at that velocity.
