Interface
*Rotary Motor Only
The MDrive34 Motion Control is
available with optional closed loop
con trol. The closed loop con fi g u-
ra tion adds a 512 line (2048 edge)
magnetic en cod er with index mark,
internal to the MDrive so there is
no in creas e in length. Func tion al ity
increases with the addition of stall
de tec tion, position main te nance,
and fi nd index mark.
In addition to an encoder option,
available motor confi gurations in-
clude a single shaft rotary motor,
a dual shaft rotary motor with rear
control knob for manual positioning,
a planetary gearbox, or a long life
Acme screw linear actuator. Rotary
versions are available in single, dou-
ble and triple stack sizes: 24, 31 &
47. In ter face con nec tions are ac-
com plished using 12.0” (30.5 cm)
fl ying leads.
The MDrive34 Motion Control is a
compact, powerful and inexpensive
solution that will reduce system
cost, design and assembly time for
a large range of stepping motor
applications.
DESCRIPTION
The MDrive34 Motion Control of-
fers the sys tem de sign er a low
cost, in tel li gent motion con trol ler
in te grat ed with a NEMA 34 high
torque step ping motor and a +24
to +75 volt microstepping driver.
The MDrive34 Motion Control adds
a versatile array of func tions by com-
bin ing a complete pro gram ma ble
mo tion controller with our already
com pact and cost ef fec tive stan-
dard MDrive34, adding little cost
and no increase in size. Stan dard
of fer ings include four +5 to +24 volt
general pur pose I/O lines, one 10
bit analog in put, 0 to 5MHz step
clock rate, microstep res o lu tion up
to 51,200 steps per rev o lu tion,
and a full fea tured easy-to-program
in struc tion set.
The MDrive34 Motion Control
com mu ni cates over RS-485 which
al lows for point-to-point or multiple
unit con fig u ra tions utilizing one
com mu ni ca tion port. Addressing
and hard ware support up to 62
uniquely addressed units com mu -
ni cat ing over a single line. Baud
rate is selectable from 4,800 to
115K.
