| RD021M8
Description |
| The
RD-021M8 is NetMotion's smallest driver ever. Though it is extremely
compact, this inexpensive, off-the-shelf driver with heat sinks
still has high performance features such as selectable microstep
and clock. Its low current makes it ideal for 11 ~ 23 frame size
step motors. Low voltage capability allows it to be used in applications
powered by a 12V battery. |

| What
is Zero Crossing?
Stepper motors have a natural tendency to want to move
towards their full step ON position. This magnetic pull
is called the detent torque of the motor, which causes a
jerking motion as the motor nears these positions. In a
bipolar stepper motor, one phase will have 100% current
and the other phase will have 0% current (this is what we
call the zero crossing point). Phases A and B are 90°
offset and both have a sinusoidal current waveform when
microstepping.
Drivers that output a perfect sinusoidal
current waveform will not have perfect accuracy. Engineers
in the Motion Control Industry have gone through trial and
error, tweaking the current sine waves in order to alleviate
the “jerk” that the motor makes as it is forcefully
pulled towards the zero crossing spots. However, altering
the waveform can greatly affect other areas of the driver’s
performance.
Since these zero crossing spots are sensitive to the minimal
amount of change, the R325 outputs the right amount of both
holding and running current into the motor to overcome the
motor’s detent torque. Thus eliminating the "jer"
at Zero Crossing and producing the smoothest microstepping
motion possible.

The

Try switching the R325 to TEST mode by placing
a jumper on Pins 9 & 10 of JP2. The motor
should twitch back and forth slightly if the R325
is functioning properly. |
