ADJUSTABLE TRIMPOT
The potentiometer shown on the board can be rotated using a screwdriver. It’s recommended to rotate the motor at 0.25 RPS. Then to adjust the potentiometer until there is the least amount of vibration and noise coming out of the motor. This will be the position that the driver will perform smoothly with a given motor and power supply voltage.
The adjustment will alter the current waveform coming out of the driver and into the motor coils.
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.
