Introduction :
The M415B is a very small size high performance microstepping drive based on one of the most advanced technologies in the world today. It's suitable for driving any 2-phase and 4-phase hybrid stepping motors. By using advanced bipolar constant-current chopping technique, it can output more speed and power from the same motor, compared with traditional drives such as L/R drives.

PUL |
Pulse signal: This input represents pulse signal, effective for each rising edge; 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. For reliable response, pulse width should be longer than 1.5ms. Series connect resistors for current-limiting when +12V or +24V used. |
|
DIR |
Direction signal: HIGH/LOW level signal, correlative to motor rotation direction. For reliable response, DIR must be ahead of PUL by 5ms at least. 4-5V when DIR- HIGH, 0-0.5V when DIR-LOW. Motor rotation direction also depends upon the connection of the motor windings, exchange any motor phase can reverse motor rotation direction. |

OPTO |
Opto-coupler power supply, and the typical voltage is +5V. |
|
ENA |
Enable signal: This signal is used for enabling/disabling drive. High level for enabling drive and low level for disabling drive. Usually left unconnected (enabled). |

Selecting Microstep Resolution and drive Output Current
This drive uses a 6-bit DIP switch to set microstep resolution, and motor operating current, as shown below:
Microstep Resolution Selection
Microstep resolution is set by SW4, SW 5, SW 6 of the DIP switch as shown in the following table:
