Superior low vibration and noise characteristics allowing for maximum motor torque output. Low vibration and noise are now possible across all speed ranges with the Smooth Drive Function.
Smooth Drive Function
The Smooth Drive Function automatically controls the stepper motor's microstep drive operation at the same travel and speed as in the full-step mode, without the operator having to change the speed settings of the driver's pulse input. It enables low-vibration operation available with the microstepping drive to be achieved with the flick of a switch.

Microstep Function
The microstepping driver electronically divides the basic step angle of the motor (1.8°/step) by up to 128 steps without the use of a reduction mechanism or other mechanical element. 16 different resolutions levels are available. The available range of resolution settings is 200 (1.8°/step) to 25600 (0.0140625°/step). The step angle can be easily set using the built-in switches on the driver. This function enables low-vibration and low-noise operation.

Third Harmonic Waveform Correction Function
This function corrects stepper motor drive current waveforms. It provides improved angle accuracy and reduced vibration.

Vibration Suppression Function
This function improves vibrations in the medium speed range of stepper motors. It enables reduced risk of missteps due to vibrations.

Wide Voltage Range Driver
The RBD Series driver utilizes a constant current driver with a wide voltage range of 20 to 75 VDC (20 to 40 VDC for lower amperage motor requirements). This enables the driver to support a wide range of power sources. Raising the power supply voltage enables increased torque during high speed operation.

Alarms
Monitor the driver performance for early detection of any abnormalities. All RBD drivers have built in alarms to alert when there is a problem. The alarms are both a blinking LED and an Alarm signal to an upper controller. Alarms range from Overheat, Overvoltage and Overcurrent.
