CZZL XY-SMD4 / XY-SMD6 Integrated Stepper Motor Controller with Modbus

CZZL XY-SMD4 / XY-SMD6 Stepper Motor Controller

An integrated single-axis drive and front-panel controller for two-phase, four-wire stepper motors. It combines local motion control, parameter storage, limit-switch inputs, and TTL serial Modbus integration for prototypes and general industrial automation.

Choose the Drive Rating

• SMD4: for 42 / 57 series stepper motors, up to 4 A drive capacity; supports full, half, 4, 8, 16, and 32 microstep settings.
• SMD6: for 42 / 57 / 86 series stepper motors, up to 6.6 A peak drive capacity; supports 8, 16, 32, and 64 microstep settings.
• Axis type: single-axis, two-phase, four-wire stepper motors with common-cathode signaling.
• Supply range: DC 10–30 V.

Control Functions

• Manual, automatic, setup, and serial-control modes with power-off parameter retention.
• Position, angle, rotational-speed, distance, acceleration/deceleration, and cycle-operation settings.
• Pulse-frequency range: 100–80,000 Hz; speed class range: 0–1000.
• TTL serial interface using standard Modbus protocol for PLC or controller integration.
• Three limit-switch inputs for home, forward, and reverse travel; external start/stop and direction inputs are also provided.

Protection and Installation

• Reverse-polarity and over-temperature protection, with active cooling; the fan is stated to start above 55°C and stop below 50°C.
• Approximate controller size: 86 × 45 × 41 mm; recommended panel opening: 81.6 × 40.6 mm.
• Set current limit, microstep resolution, electronic gearing, and travel parameters to match the specific motor and mechanical load before operation.
• Disconnect power before wiring motor phases, DC supply, limit switches, or serial-control terminals.
