Microstep Chopper Driver

• Drives a two-phase bipolar stepper motor using constant-current chopper regulation.
• DIP switch addressable; stack up to 32 modules on the same serial port for multiple axes.
• User programmable drive current and idle reduction current. Independent of power supply voltage.
• Select up to 64 microsteps per step.
• Up to 10,000 pps step rate.
• S-curve acceleration and deceleration slope profiles provide smooth start/stop motion.
• Supports move-to-coordinate, move-to-limit-switch, and continuous-rotation modes.
• 24-bit absolute motor position counter.
• Two normally-open limit switch inputs.
• All user configuration data stored in non-volatile memory.
• Automatic thermal shutdown protects motor driver Power MOSFETs from overheating.
• Wide power supply range (8 to 30 VDC).
• Optional enclosure also available.

Connects to a PC or Laptop using our USB Cable or to any other host which incorporates an RS-232 serial port. Stack multiple cards together on the same port. This module is a complete stepper motor driver and intelligent controller built into one. Simple coordinate commands sent from the host will advance the motor to an exact position in the range of 0 to 16,777,215 using S-curve acceleration/deceleration slope profiles which reduce stall effects during ramping, and overrun effects during breaking. Host can also instruct the motor to accelerate to a target velocity and continue to move until a limit switch triggers the deceleration curve, or rotate continuously while the host controls the velocity on the fly. Ideal for use in cost sensitive, open-loop, precision motion control applications requiring a minimal user learning curve.
