Bipolar Step Motor Driver Operates from 24 to 80 VDC Phase current ranges from 1 to 7 Amps AND 0.3 to 2 Amps 10 Microstepping Driver Optically isolated Step, Direction, and Disable/Enable Inputs Selectable Current Reduction of 33% Low Power Dissipation Step Frequency of 20 KHz Efficient Current Control Power-on Indicator Power Disable/Enable Control Sinusoidal current waveform Low Cost Driver
Microstepping Driver R208
Microstepping Driver R325
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.
INPUT VOLTAGE: +24 to 80 VDC
DRIVE CURRENT(PER PHASE): 0.3 to 2 Amps OR 1 to 7 Amps
