*Rotary Motor Only

The MDrive34 Motion Control is
available with optional closed loop
con trol. The closed loop con

fi g


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
