Fig. 4-2: Determining the times for isochrone mode
1st example:
One magnet with a 500 mm nominal stroke
(selected module:: 1 Position inserted)
From the table in Fig. 4-2 T
Signal
is shown as 260 µs. T
Calc
is
calculated as follows:
T
Calc
= (Number_of_magnets × 15 µs) + 340 µs
= (1 × 15 µs) + 340 µs
= 365 µs
T
Calc
is then greater than T
Signal
which means for T
DP
:
T
DP
≥ T
Signal
+ T
Calc
= 260 µs + 365 µs = 625 µs
Since the cycle time is not less than 625 µs, T
DP
can be set
to 625 µs or greater (e.g. 1 ms). Time T
I
should be at least
as great as T
Calc
. For T
DP
= 625 µs T
I
can then be 365 µs.
T
O
can be selected between 125 µs and T
DP
–T
I
= 625 µs
– 365 µs = 260 µs.
2nd example:
FMM mode with 7000 mm nominal stroke.
Selected module: FMM with Position and Speed
From the table in Fig. 4-2 T
Signal
is 2760 µs. T
Calc
and
thereby the minimum input time T
I
is 765 µs in FFM mode
with speed. This means the minimum cycle time is T
DP
3525 µs.
