Description

The DM422 is a versatility fully digital stepping driver 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 self-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 drives on the markets. Its unique features make the DM422 an ideal solution for applications that require low-speed smoothness. Compared to the DM422C, the DM422 offers better high speed performance and the user can configure the standstill current in the software. What's more, a pulse filter has been built into the DM422.
* Pb-Free or CE/UL approved versions optional. Contact Leadshine or see more information in its hardware manual please.

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 7.5µs. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signals.

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.

OPTO

Opto-coupler power supply, and the typical voltage is +5V. Series connect resistors (at the PUL, DIR, ENA terminals) for current-limiting when +12V or +24V used.

ENA

Enable signal: This signal is used for enabling/disabling driver. High level for enabling the driver and low level for disabling the driver. Usually left UNCONNECTED (ENABLED).

Microstep & Current

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 0.3A to 2.2A.


However, when it’s not in software configured mode, this driver uses a 6-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 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.
