A - GS-D500ADESCRIPTION
The
GS-D500A
is a complete subsystem to drive
steppermotorseitherinfullstepor microstepmode.
Averylarge numberof auxiliaryfunctionshasbeen
included toallow extremesimplicity andflexibility in
use.
Particularcarehas beendevotedto protections,so
thatthe
GS-D500A
canbesafelyusedinveryharsh
environments.
In additiontotheobviousfunctionto drivethemotor
phasesina choppingmode, thefollowing functions
havebeen implemented:
-
Sine/cosinegeneration
-
Selectionofthree differentmicrosteps/steprates
-
Selection of full/half step drive
-
Programmingofpeakphasecurrenttooptimize
the torque
-
Automatic phase current reduction at rest (se-
lectable)
Full protection against short-circuit between
phase-to-phaseandphase-to-ground
Thermal and undervoltageprotection
Galvanic isolation of 3 input signals (
clock,
direction,zero current
).
Fault indication output
On boardauxiliary voltages generation
Midrangestability circuitry (selectable)

As aresult, the
GS-D500A
canprovideupto5Aper
phase and, in its simplest application, just three
command signals are required:
step clock, direc-
tion, disable.
