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...10Ăms). Since this time
interval is usually longer than a position controller cycle
(350 Ģs, the controller independently interpolates the values
between two specified position values. At every specified
interval, the CDIR.B4 CONTT (Toggle−Bit") must be toggled
to ensure that any new interval is recognised.
