Features
The
DM556 is a versatility fully digital stepping drive based on a DSP with
advanced control algorithm. It brings a unique level of system smoothness,
providing optimum torque and nulls mid-range instability. The Self-test and
auto-configuration technology offers optimum responses with different motors
and easy-to-use. The driven motors can run with much smaller noise, lower
heating, smoother movement than most of the drives in the markets. Its unique
features make the DM556 an ideal solution for applications that require
low-speed smoothness.

PUL+
|
Pulse
signal: In single pulse (pulse/direction)
mode, this input represents pulse signal, each rising or falling edge active
(software configurable); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double
pulse mode (pulse/pulse) , this input represents clockwise (CW) pulse,active
both at high level and low level (software configurable). For reliable
response, pulse width should be longer than 2.5µs. Series connect resistors
for current-limiting when +12V or +24V used. The same as DIR and ENA signals.

|
PUL-
|
|
DIR+
|
DIR signal: In single-pulse mode, this signal has low/high voltage
levels, representing two directions of motor rotation; in double-pulse mode
(software configurable), this signal is counter-clock (CCW) pulse,active both
at high level and low level (software configurable). For reliable motion
response, DIR signal should be ahead of PUL signal by 5µs at least. 4-5V when
DIR-HIGH, 0-0.5V when DIR-LOW. Please note that rotation direction is also
related to motor-drive wiring match. Exchanging the connection of two wires
for a coil to the drive will reverse motion direction.

ENA+

Enable
signal: This signal is used for
enabling/disabling the drive. High level (NPN control signal, PNP and
Differential control signals are on the contrary, namely Low level for
enabling.) for enabling the drive and low level for disabling the drive.
Usually left UNCONNECTED (ENABLED).

Microstep
resolutions and output current are programmable, the former can be set from
full-step to 102,400 steps/rev and the latter can be set from 0.5A to 5.6A.
However, when it's not in software configured mode, this drive uses an 8-bit
DIP switch to set microstep resolution, and motor operating current, as shown
below:
Microstep
Resolution Selection
When it's not in
software configured mode, microstep resolution is set by SW5, 6, 7, 8 of the
DIP switch as shown in the following table:

Current
Settings
When it's not in
software configured mode, the first three bits (SW1, 2, 3) of the DIP switch
are used to set the dynamic current. Select a setting closest to your motor's
required current.
