Introduction

The DM320C is a versatility fully digital stepping driver based on a DSP with advanced control algorithm. The DM320C is the next generation of digital stepping motor controls. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. Motor self-test and parameter auto-setup 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 in the markets. Its unique features make the DM320C an ideal solution for applications that require low-speed smoothness. Compared to the DM422C, the DM320C is more compact and lower cost.

Pin Assignment and Description

Connector P1 Configurations

Pin Function

Details

PUL+

Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each rising edge active; 4-5V when input is HIGH, 0-0.5V when input is 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 6.7?s. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signals. (Note: CW/CCW mode is not supported by standard version and need to be specified when place order.)

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 5?s at least. 4-5V when DIR input is HIGH, 0-0.5V when DIR input is 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 driver. High level for enabling the driver and low level for disabling the driver. Usually left UNCONNECTED (ENABLED).

ENA-

ALM+

Enable signal: Alarm signal output. OC output, high impedance when the working status is normal and low impedance when over-voltage, over-current, phase error activate.

Selecting Microstep Resolution and Drive Output 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 2.0A.

Note: Microstep and output current programmable feature is reserved and not offered by standard version, because the RS232 connector of standard version is not installed on standard model.

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.
