1 RoHS-Compliant -Phase Stepping Motor and Package RBK Series Microstep Drive -phase stepping motor and DC input microstep driver in one package. Includes Oriental Motor's proprietary Smooth Drive Function, to easily achieve low-vibration operation.

2 Adopting a Compact and High Performance Microstep -Phase Stepping Motor and Package RBK Series -phase stepping motor and DC input microstep driver in one package. Includes Oriental Motor's proprietary Smooth Drive Function, to easily achieve low-vibration operation. Smooth Drive Function The Smooth Drive Function is a function that automatically controls the motor's microstep drive operation at the same travel and speed in the full-step mode, without the operator having to change the speed settings of the driver's pulse input. It enables the low-vibration operation available with the microstepping drive to be achieved with the flick of a switch. Vibration Component Voltage Vp-p[V] RBKT Power Input: VDC Load Inertia: JL= kg m Smooth Drive Function: Deactivated Smooth Drive Function: Activated Microstep Function The microstepping driver electronically divides the basic step angle of the motor (1. /step) by up to 1 without the use of a reduction mechanism or other mechanical element. 1 different resolutions are available. The available range of setting is resolution (1. /step) to (.1 /step). The step angle can be easily set using the built-in switches to the driver. This function enables low-vibration and low-noise equipment. Vibration Component Voltage Vp-p[V] RBKT Power Input: VDC Load Inertia: JL= kg m

3 Third Harmonic Waveform Correction Function This function corrects motor drive current waveforms. It provides improved angle accuracy and reduced vibrations. Vibration Component Voltage Vp-p[V] RBKT Power Input: VDC Load Inertia: JL= kg m Third Harmonic Waveform Correction Function: % Third Harmonic Waveform Correction Function: -% 1 3 Vibration Suppression Function This function improves vibrations at medium speed range of the stepping motor. It enables reduced risk of missteps due to vibrations. Vibration Component Voltage Vp-p[V] RBKT Power Input: VDC Load Inertia: JL= kg m PULLOUT Vibration Suppression Function: Deactivated Vibration Suppression Function: Activated Conforming to Major Safety Standards The RBK Series is UL-recognized and CSA-certified. It also bears the CE Mark as a proof of conformance to the Low Voltage Directives. RoHS-Compliant The RBK Series conforms to the RoHS Directive that prohibits the use of six chemical substances including lead and cadmium. RoHS (Restriction of Hazardous Substances) Directive: Directive on restriction of the use of certain hazardous substances in electrical and electronic equipment (/9/EC). The RoHS Directive prohibits the use of six chemical substances in electrical and electronic products sold in the EU member states. The six controlled substances are: lead, hexavalent chromium, cadmium, mercury and two specific brominated flame-retardants (PBB and PBDE). The motor conforms to the IP standard of ingress protection against dust and water. Terminal-Block Connection Design The motor can be wired directly from its terminal block Adoption of Wide Voltage Range The RBK Series adopts a constant current driver with a wide voltage range of to 7 VDC and. A/phase effective value (.3 A/phase peak value). This enables it to support a wide range of power sources. RBKT equips a constant current driver with a voltage range of to 7 VDC and. A/phase effective value (.9 A/ phase peak value). Comparison of Speed - Torque Characteristics Current:. A/Phase ( Phases ) Step Angle: 1. /step Load Inertia: JL= kgm VDC Input 7 VDC Input Terminal Box No Motor/ Relay Since the motor cable can be connected directly with the driver terminals, there is no need for wire connection or soldering on a relay terminal block. Motor Raising the power supply voltage enables increased torque at high-speed operation. Cable (The cable for connecting the motor and driver must be purchased separately.) 3

Line driver input is also available. The pin No. to connect differs according to the signal voltage. All Windings Off (AWO) and Step Angle Select (CS) Input Connections You can select either VDC or VDC as the signal voltage. The pin No. to connect is the same for VDC and VDC. Connecting Output Keep the output signal voltage and current below 3 VDC and 1 ma respectively. Power Supply Use a power supply that can supply sufficient input current. When power supply capacity is insufficient, a decrease in motor output can cause the following malfunctions: Motor does not operate properly at high-speed. Slow motor startup and stopping. Notes on Wiring Use twisted-pair wires of AWG (.1 mm ) or thicker and m or less in length for the signal lines. Note that as the length of the pulse signal line increases, the maximum transmission frequency decreases. Use wires of AWG1 (.7 mm ) or thicker for motor lines (when extended), power supply lines, and protective earthing line. To ground the driver, lead the ground conductor from the protective earth terminal (M) and connect the ground conductor to provide a common ground point. lines should be kept at least cm away from power lines (power supply lines and motor lines). Do not bind the signal lines and power lines together. If noise generated by the motor cable or power cable becomes a problem due to the wiring and layout, shield the cables or use ferrite cores. Incorrect connection of DC power input will lead to driver damage. Make sure that the polarity is correct before turning power on. The cable for connecting the motor and driver, and the D-Sub (1-pin) connector for connecting to the driver's CN1 connector are not included. They must be purchased separately.

Pulse Characteristics Keep the pulse signal at the "photocoupler " state when no pulses are being input. Leave the pulse signal at rest ("photocoupler ") when changing rotation directions. All Windings Off (AWO), Step Angle Select (CS) Input Input Circuit and Sample Connection Open-Collector Output V 3 kω CW CW V, 1 ma All Windings Off (AWO) Input Inputting this signal puts the motor in a non-excitation (free) state.

All Windings Off Motor Current Motor Holding Torque Release Switching the "All Windings Off" signal from "photocoupler " to "photocoupler " does not alter the excitation sequence. When the motor shaft is manually adjusted with the "AWO" signal input, the shaft will shift up to 3. from the position set after the "AWO" signal is released. 1

13 Step Angle Select (CS) Input When the signal is at "photocoupler," the motor operates with the basic step angle, regardless of the setting of the step angle setting switch. When the signal is at "photocoupler," the motor operates with the step angle set with the step angle setting switch. When changing the step angle, make sure the "Excitation Timing" signal output is turned on and the motor is at standstill.

When using the "Excitation Timing" signal output, operate the motor so that its output shaft stops at an integral multiple of s.3 s 1. s When the motor is running, if the driver overheat, overvoltage, or overcurrent protective function is detected, the ALM output turns off, and the ALARM LED of the driver flashes. The current to the motor is also cut off to stop the motor. You can count the number of times the ALARM LED flashes to confirm which protective function is activated.
