Introduction
|
|
The DMD5056 driver is a new model of stepper motor driver based on DSP technology. It brings a very significant gain for the use of stepper motors and in particular, thanks to the principle of current regulation and to the breakdown of the variable steps according to the speed, it is possible to make the best use of the characteristics of your stepper motors. This technology results in optimum torque, low vibration and reduced heating.
The driver therefore makes it possible to obtain operation close to that of a DC motor even for low rotational speeds.
|
Applications
|
|
Usable with NEMA 17, 23 and 34 size motors, this driver is particularly recommended for 57CM13 and 57CM26 motors in the SOPROLEC range. Used in placement applications and XY tables, this driver will give you optimum operation with reduced noise.
Tuning by serial link allows to adjust the settings of the driver in an optimum way.

PUL﹢(+5V)
|
Pulse signal: in single pulse (pulse/direction) mode, this input
represents pulse signal, effective for each rising edge; 4-5V when
PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) this
input represents clockwise (CW) pulse. For reliable response, pulse
width should be longer than 2.5us. Series connect resistance for
current-limiting when +12V or +24V used.

PUL- (PUL)
|
|
DIR+ (+5V)
|
DIR signal: HIGH/LOW level signal, corresponding to motor rotor
direction. For reliable response, DIR must be ahead of PUL by 5ms at
least, the initial motor direction is related with motor wiring,
exchange any set of coil can reverse motor initial direction. 4-5V when
DIR- HIGH, 0-0.5V when LOW.

Enable signal: this signal is used for enabling/disabling the driver.
High level for enabling the driver and low level for disabling the
driver. Usually left unconnected (enabled).
