The DM1182 is a high voltage, 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. Motor auto-test and parameter 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 drivers on the markets. Its unique features make the DM1182 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-driver wiring match. Exchanging
the connection of two wires for a coil to the driver will reverse motion
direction.
|
|
DIR-
|
|
ENA+
|
Enable signal: This signal is used for enabling/disabling the driver. High
level (NPN control signal, PNP and Differential control signals are on the
contrary, namely Low level for enabling.) for enabling the driver and low
level for disabling the driver. Usually left UNCONNECTED (ENABLED).
When use it, the ENA signal should ahead the PUL signal at least 100ms due to
of soft-start feature of the DM1182.
|
|
ENA-
|
|
FAULT+
|
Fault Signal: Open collector fault output. High impedance between FAULT+ and
FAULT- during normal operation and low impedance when over-voltage,
under-voltage, over-current and phase error protection. MAX: 30VDC, 20mA.

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 8.2A .
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.
