Ratings of 35V:a max value of 33V is reccom-
mended.
In this case, at each couple of outputs for the bi-
polar windings, a snubber network must be con-
nected. This network is done by the series of a re-
sistor and of one capacitor:
Rsnub = VS max/Imotor peak;
Csnub = Imotor peak/ (dv/dt)
One dv/dt of 200V/
sec is generally a correct
choice.
Of course, care must be taken in the Printed Cir-
cuit Board design regarding the ground paths and
the high current loops.
An example of P.C.B. layout is shown in Figure
29ab; Figure 30 shows the Schematic Diagram of
the circuit of the L6280 S.P.D. S.AB.
The driving signals useful for this board can be
easily generated by using an additional board
(EMU KIT 512) not described here.
On Figure 29a it can be observed the copper area
near the I.C. is used to sink out the heat from the
device. Useful thermal characteristics of the
L6280 are shown in Figure 31 and 32.
