The times stated in the diagrams have a tolerance of +/- 100
µ
s. This tolerance has to be taken into
consideration in addition to the times given in the timing diagrams!
The DUET_FL position controller has a sequential control with a time base of 1.6 ms. The
statuses of the digital inputs and outputs are checked and updated cyclically.
The cycle time of the SPC or of the control must be set to values < (1.6 ms – 100
µ
s) =
1.5 ms so that the SPC can detect all messages from the DUET_FL. On the other hand,
all the control signals from the SPC must be applied > (1.6 ms + 100
µ
s) = 1.7 ms in
order to ensure that the DUET_FL can recognize the signals correctly.
Example: SPC with t
cycle
= 1 ms
→
setting of the SPC outputs for at least 2 x t
cycle
= 2 ms

-
t2 > 1.6 ms
-
t3
≈
10 ms Depends on the operating mode and on the status of the drive
-
t4 = N x 1.6 ms Can be parameterized (run delay braking parameter)
-
t5 < 1.6 ms
-
t6 = N x 0.2 ms Depends on the quick stop ramp
-
t7 = N x 1.6 ms Can be parameterized (stop delay braking parameter)
