Let’sassume the following valuesare needed:
I
rest
= 0.25A
I
ramp
= 1.5A
I
slew
= 0.5A
The logic condition ofthe RAMPand MOV outputs
in the various states is:
During the ramping phase both pins 22 and
23 are high: Tr1 is ON and Tr2is OFF.
During the slew phase pin 23 is low and pin
22 is high: Tr1and Tr2 are OFF.
In stall condition Tr1is OFF and Tr2 is ON.
The value of R1, R2, R3 is determined as follows
(for further details please see the GS-D200/200S
data sheet). The value of R3, that fixes the I
slew
=
= 0.5A (Tr1 and Tr2 OFF), is easily calculated by
referring to the GS-D data sheet:
R3
=
I
slew
1
0.933
I
slew
R3
=
937
The value ofthe R2resistor, when paralleled to R3,
fixes the value of I
rest
= 0.25A (Tr1 OFF, Tr2ON).
R2 //
R3
=
I
rest
1
0.933
I
rest
R2 // R3 = 326
R2 = 500
The value of R1, that depends on the value of R3
and the resistors contained in the GS-D200/200S
module, fixes I
ramp
= 1.5A(Tr1 ON, Tr2OFF).
The valuesof the internal resistors are:
1.2k
to ground and 10k
to V
SS
for the
GS-D200
750
to ground and 10k
to V
SS
for the
GS-D200S
Assuming the GS-D200S is used, after some
straightforward calculations,it results:
R1 = 4245
of course allthese values donottake into account the
transistorssaturation losses and in somecases, when
a veryprecise currentisneeded,atrimming isrequired.
GALVANICISOLATION
The industrial environment, where normally a step-
per motor and its driving system operate, is very
noisy andfor thisreason itisoften advisableto have
a galvanicisolation between the Host computerand
the motion system. Because the connection bet-
ween the Host and the GS-Cmodule requires only
three wires (TxD, RxD and ground), the galvanic
isolation can be implemented as per fig. 12 that
uses only two optocouplers and two resistors, one
protection diode and a +12 or +15V source.
A +12 or +15V source is normally available on the
pin 6 and 8 of any RS232 connector. The source
impedance is quite high (in the range of 220 to
600
) and for this reason the value of R2 must be
greater than 1000
to avoid the source overload.
