Oriental Motor RBD200A-V Stepper Driver – 20–75 V DC, 2-Phase, Microstep

Encased microstep driver from Oriental Motor (RBD series, legacy). Wide 20–75 V DC supply (use a power supply rated ≥ 5.2 A), photocoupler inputs (5–24 V), and functions to reduce vibration and noise (Smooth Drive, anti-resonance). Up to 128-way microstepping (1.8° → 0.014°) with adjustable motor current up to 4.5 A/phase and alarm/monitor outputs. Suitable for 2-phase bipolar stepper motors in CNC and automation.

Features:

• Brand: Oriental Motor
• Series: RBD (legacy)
• Model (MPN): RBD200A-V
• Driver Type: 2-phase bipolar, pulse input
• Supply: 20–75 V DC (power supply ≥ 5.2 A recommended)
• Microstepping: up to 128 divisions (1.8° to 0.014°)
• Logic I/O: 5–24 V photocoupler inputs (PNP/NPN)
• Outputs: ALM (alarm), CD (current-cutback), TIM (home timing), open-collector
• Functions: Smooth Drive, anti-resonance, current cutback, 3rd-harmonic correction
• Mounting: DIN-rail plate / panel mount

Technical Specifications:

• Operating current (settable): 0.08–4.5 A/phase (dial RUN + SW1)
• Max response frequency: 250 kHz (up to 500 kHz in line-driver mode)
• Step angle presets: 16 levels (1, 2, 4, 5, 8, 9, 10, 16, 18, 20, 32, 36, 40, 64, 80, 128)
• Outputs rating: open-collector ≤ 30 V DC, ≤ 10 mA
• Wiring guidance: power cable AWG18 (≤ 2 m), I/O AWG26 (≤ 2 m); PE grounding
• Compliance: EMC immunity per EN 61000-6-2 (see manual)

Key Benefits:

• Smoother motion: Smooth Drive & anti-resonance reduce low/medium-speed vibrations.
• Flexible resolution: up to 128 microsteps for finer positioning.
• Robust integration: wide DC input, 5–24 V logic, alarm and timing outputs.

Important Notes:

• Use a DC supply with reinforced insulation; add an EMC mains filter (e.g., Schaffner FN2070) on the PSU input.
• Observe polarity, grounding (PE) and cable length limits; see operating manual for wiring details.
• VAT invoice available on request.
• 30-day returns accepted; buyer pays return shipping.
