5.6.7 Direct mode: Continuous setpoint specification (Continuous Mode)
With continuous setpoint specification (Following mode) the
higher level controller continuously specifies position values
at fixed time intervals
(typically 4 ... 10ms). Since this time
interval is usually longer than a position controller cycle
(350s , the controller independently interpolates the values
between the specified position values. At every specified
interval, the CDIR.B4 CONTT (Toggle Bit") must be toggled to
ensure that any new
interval is recognised.
