R710 - includes a built-in Step Pulse Multiplier board
The R710 has the same features as the R701 plus two additional features:
Input Option Header - allows the use of a Common Ground or a Common +5VDC for optically isolated inputs
Step Pulse Multiplier - will always output 10 microstepping, even with a step input of Full Step, Half Step, 5 Microstep, or 10 Microstep. The user no longer needs to change their original setup to get microstepping. Simply select the desired step multiplier of 1, 2, 5 or 10; to achieve the 10 microstepping output from the driver, while maintaining the rotational speed that you had in your original setup.
