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.

Smooth Drive Function

The Smooth Drive Function automatically controls the 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.

Third Harmonic Waveform Correction Function

This function corrects 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 RBK Series utilizes a constant current driver with a wide voltage range of 20 to 75 VDC (20 to 40 VDC
for High-Torque and Planetary Geared models). This enables it to support a wide range of power sources and raising the power supply voltage enables increased torque during high speed operation.

 

NOTE: Raising the power supply voltage enables increased torque during high speed operation.

High Torque Type

The high-torque type adopts new technology and design. The motor produces approximately 30 ~ 50% higher torque than a conventional stepper motor of the same size.

General-Purpose Cables

These are dedicated 15-conductor cables for connecting the I/O signal connector and programmable controller. They are high-quality noise-blocking, double shielded cables.

Encoder Cable
(included with package)

This encoder cable is available for use with the appropriate motors with encoders. [An encoder cable of 2 ft. (0.6 m) is included with the motor with encoder and driver packages.]

 

Clean Dampers

Mechanical dampers suppress stepper motor vibration and improve high-speed performance. An inertia body and silicon gel are hermetically sealed in a plastic case.

(For use with Double Shaft motors)

 

Cables / Connectors

Connection Cable for Terminal Box Type Motor

A cable for connection between the terminal box type and driver (with protective earth wire)

Connection Cables for Connector Type Motors
(included with package)

This lead wire connection cable with a conveniently crimped connector is for connector-coupled motor, and for connecting motors and drivers. [A connection cable of 2 ft. (0.6 m) is included with the motor with connector and driver packages.]
