GS-DC200 Family
STEPPER MOTOR CONTROL AND DRIVE SYSTEM FAMILY
DESCRIPTION
The GS-DC200 series is a family of single Eurocard
boards that contain all the logic necessary to oper-
ate a stepper motor, including the instructions de-
coding, the step timing generation, the storage of
the program to be executed. The motor interface
can deliver phase current up to 2.5A.
The boards can be used as a stand alone complete
motion control system or they can be driven by a
central host computer.
The GS-DC200 family isbuilt around the GS-C200,
GS-C200S, GS-D200, GS-D200S modules, (see
the relevant data sheet) and it retains all the fea-
tures of these modules.

USER NOTES
1 A GS-DC 200
2 A GS-DC200S / GS-DC200SS.
To correctly operate the GS-DC boards family, it is
recommended to read the following data sheets:
GS-C200/200S; GS-D200/200S; GS-C200 PROG.
The new value of R resistor for a different value of
x
maximum phase current I (A) can be calculated
according to the following formulas:
Supply Voltage
The recommended operating maximum supply volt-
GS-D200
age must include the ripple voltage on the V supply
s
I > 1,07
rail and it must not exceed 40V to avoid permanent
damage to the board.
10 – I
(0.993 I) –1
Rx = [
Rx = [
Rx = [
Rx = [
] kΩ Rx ≥ 8.2KΩ
The boards have internal capacitors connected be-
tween the supply and ground pins to assure the
electrical stability. These capacitors cannot handle
high values of current ripple and they would be
permanently damaged if the voltage source imped-
ance is not adequately low.
I < 1,07
I
] kΩ
1– (0.993 I)
GS-D200S
The use of a low ESR, high current ripple,
470µF/50V capacitor located as close as possible
to the board is recommended. Suitable units are the
Sprague type 672 D or 678 D, the RIFA type PEC
126 or any equivalent unit.
I > 2,11

I < 2,11
Board Protections
I
The GS-DC200 board is protected against occa-
sional or permanent short circuits to the supply
voltage of the phase output pins.
] kΩ
3.03– (1,43 I)
The maximum programmed current must not ex-
ceed 2.0A for the GS-DC200 and 2.5A for the
GS-DC200S/GS-DC200SS.
The GS-DC200S and GS-DC200SS are protected
also against short circuits to ground or to another
phase output.
Thermal Characteristics
For the GS-DC200S and GS-DC 200SS the protec-
tion is of the latching type i.e. when an overload
occurs, the board is automatically disabled. To re-
start the operations, the supply voltage must be
switched off for at least 100 ms.
The maximum power dissipation occurs on the
GS-D200/GS-D200S modules usedon the boards.
The thermal resistance case-to-ambient of the inte-
gral heatsink of these modules is 5°C/W. This
means a 50°C temperature increase of the heatsink
if the internal power dissipation is 10W.
Motor Connection
When long wires are needed to connect a remote
motor, it is recommended to use twisted pair cables
with a proper cross section to minimize DC losses
and RFI problems.
The maximum allowed heatsink temperature is
85°C. Therefore, according to the ambient tempera-
ture and/or the internal power dissipation, forced
ventilation may be required.
Programming
Phase Current Programming
To correctly program motion sequences, see the
GS-C200/200S and/or GS-C200 PROG data
sheets.
The maximum output current/phase can be pro-
grammed by changing the value of the R resistor.
