Introduction:
The XDM-70 is a high performance microstepping drivers based on
pure-sinusoidal current control technology. Owing to this
advanced technology, the driven motor can run with smaller noise,
lower heating, smoother movement and have better performance
at higher speed than most of the drivers in the markets. It is
suitable for driving 2-phase and 4-phase hybrid stepping motors.
Applications
Suitable for a wide range of stepping motors, from NEMA size 17 to 43. It
can be used in various kinds of machines, such as X-Y tables, labeling
machines, laser cutters, engraving machines, pick-place devices, and so
on. Particularly adapt to the applications desired with low noise, low
heating, high speed and high precision.

Pulse signal: In single pulse(pulse/direction) mode,
this input represents pulse signal, effective for each
rising or falling edge(set by inside jumperJ1);4-5V
when PUL-HIGH,0-0.5V When PUL-LOW. For
reliable response, pulse width should be longer than
1.5 μ s. Series connect resistors for
current-limiting when +12v or +24v used.
DIR signal: In single-pulse mode, this signal has
low/high voltage level, representing two directions of
motor rotation; For reliable motion response, DIR
signal should be ahead of PUL signal PUL signal by 5
μ s. at least.4-5V when DIR-HIGH,0-0.5V when
DIR-LOW. Please note that motion direction is also
related to motor-driver wiring match. Exchanging the
connection of two wires for a coil to the driver will
reverse motion direction.
Enable signal: This signal is used for enable/disabling
the driver. High level(NPN control signal, PNP and
Different control signals are on the contrary, namely
Low level for enabling.) for enabling the driver and
low level for disabling the driver. Usually left

XDM-70 to refer. Due to motor inductance, the actual current in the coil may be
small than the dynamic current setting, particularly under high speed condition.
