Descriptions

The DM2282 is a high voltage, fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion

control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its

motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared

with traditional analog drives, DM2282 can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its

unique features make DM2282 an ideal choice for high requirement applications.

Applications

Suitable for a wide range of stepper motors, from NEMA size 34 to 51. It can be used in various applications such as laser cutters, laser

markers, high precision X-Y tables, labeling machines, CNC router, etc. Its unique features make the DM2282 an ideal choice for

applications that require both low-speed smoothness and high speed performances

Description

PUL+

Pulse Signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each

rising or falling edge active (software configurable, see DM drives software operational

manual for the detail); In double pulse mode (software configurable), this input represents

clockwise (CW) pulse, active both at high level and low level. 4-5V when PUL-HIGH,

0-0.5V when PUL-LOW. 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 signal.

PUL-

DIR+

Direction 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. For reliable motion

High Voltage Digital Stepper Drive DM2282 Manual

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. The direction signal’s polarity is software configurable.

DIR-

ENA+

Enable signal: This signal is used for enabling/disabling the drive. In default, high level

(NPN control signal) for enabling the driver and low level for disabling the driver. Usually

left UNCONNECTED (ENABLED). Please note that PNP and Differential control signals

are on the contrary, namely Low level for enabling. The active level of ENA signal is

software configurable.

ENA-

FAULT

Fault Signal: OC output signal, active when one of the following protection is activated:

over-voltage, over current, low voltage, phase error and over-temperature. This port can sink

or source 20mA current at 24V. In default, the resistance between FAULT+ and FAULT- is

high impedance in normal operation and become low when DM2282 goes into error.

FAULT

RS232 Communication Port

The RS232 communication port is used to configure the DM2282’s peak current, microstep, active level, current loop parameters and

anti-resonance parameters. See DM driver’s software operational manual for more information.

Auto-Configuration

Switch SW4 two times in two seconds will activate parameter Auto-configuration for DM2282’s current loop. That is, OFF-ON-OFF or

ON-OFF-ON. During Auto-configuration, motor parameters are identified and DM2282’s current loop parameters are calculated

automatically. The motor shaft will vibrate a little during the process of Auto-configuration which takes about 1 to 3 seconds.
