To optimize the motor torque during the accelera-
tion and deceleration (t
1
and t
3
) it is convenient to
use a phase current profile as shown in fig. 6.
Duringthe SLEWphase (t
2
) when the motor rotates
at constant speed, the current is reduced to the
minimum value necessary to compensate the sys-
tem losses (friction) and theload inertia. During the
STALL phase (t
0
and t
4
) the current is further re-
duced to the bare value necessary to maintain the
load in the right mechanical position.By using this
current profile the power dissipation of the Se-
quencer-Driver and motor isoptimized.
This profile can easily be implemented by using the
utility signals:
MOV
Movement in execution.
RAMP
Ramp in execution.

Figure 7. USEROutput Applicative Example
The statusof these two outputs can be used to set
the appropriate phase current value for the power
driver, by asimple but effective interface circuit that
is described indetail in fig. 11 of paragraph

THEUSER INTERFACE
The USER interface consists of three inputs and
three outputs which are TTL compatible. They can
be read and/or activated during the execution of a
program under the complete usercontrol; therefore
they condition a program execution.
These signals allow the implementation ofcomplex
movements, minimizingtheprogram lengthand the
useof external hardware. The start of a movement
or ofa sequence canbe conditioned bya logic level
applied to one or more inputs, thus performing the
”mechanical tree” function.
The USER outputs logic state is set by program
instructions and this information can be used by
other controllers to synchronize multiple move-
ments or to controlexternal drivers.
By using only these signals, it is possible to build
up simple systems which implement cyclic move-
ments and create a true stand-alone system. The
example reported in figure 7 shows one of the
possible utilization of USER output. The example
refers to a complete motion control system imple-
mented by using the GS-C200 controller and the
GS-D200 Sequencer-Driver. The USER output
UO1 isused to enable the GS-D200 (UO1 High) or
to inhibit it (UO1 Low).
The USER output UO2 is used to select the motor
current decay inherent to the chop mode control of
GS-D200. When UO2 is high a slow decay is im-
posed to the phase current during recirculation;
when UO2 is lowa fast decay is selected.
The USERoutputUO3allows the selectionbetween
the half and full-step mode of operation of the
GS-D200. Half-stepoccurs when UO3 is high.
The GS-C200S is capable of executing a jump
command either direct or conditioned by the logic
status of the USER inputs. This capability is very
useful because it allows complex programs to be
written by usinga limited number ofinstructions.This
feature makes also possible to have a segmented
program contained inthe internal memory; the selec-
tion and the subsequent execution of the needed
program segment is started by aspecific logic status
applied to the USERinputs.
