SMD258C Two-Phase Hybrid Stepper Motor Driver, Resolution up to 40000S/R
Overview
The SMD258C is a two-phase motor driver for hybrid stepper motors, supports 16 grades setting for both drive current and stepping subdivision, resolution up to 40000S/R. It is widely used in CNC equipment, sculpturing machine, cutting machine, etc.
Features
- Wide range voltage input (DC 24V~80V)
- 16 grades stepping subdivision setting, resolution up to 40000S/R
- 16 grades drive current setting, adjustable between 0.5A/Phase and 5.0A/Phase
- Supports three control modes: common cathode, common anode, and differential
- Supports alerts for undervoltage, overvoltage, overheat, overcurrent
- Supports phase memory when power down
- Optical isolation for both I/O signal and input signal
- When the stepping pulse stops over 100ms, coil current will be halved automatically
- Comes with development resources and manual (examples for Raspberry Pi, STM32， Arduino)
Specifications
- Operating voltage: DC 24V ~ 80V
- Signal voltage: 4.2V ~ 24V
- Drive current: 0.5A ~ 5A
