4 Axis Controller

Minitech’s advanced stepper driver is based on a DSP with an advanced control algorithm. It brings a high level of system smoothness, providing optimum torque and nulls mid-range instability. Motor auto-identification and parameter auto-configuration technology offers optimum responses with different motors and is easy-to-use. The driven motors can run with much lower noise, less heating, smoother movement than most of the drivers in the markets. Its unique features make the driver more attractive
• High Performance, Based on DSP Algorithm.
• Anti-Resonance, provides optimum torque and nulls mid-range instability Motor auto-identification and parameter auto-configuration technology, offers optimum responses with different motors
• Multi-Stepping allows a low resolution step input to produce a higher microstep output for smooth system performance
• Microstep resolutions programmable, from full-step to 51,200 steps/rev
• Can be set by Dip switch (2,4,8,16,32,64,128,256,5,10,25,50,125,250)
• Supply voltage up to +36 VDC
• Output current programmable, from 0.5A to 4.2A(Can be set by Dip switch too)
• Pulse input frequency up to 200 KHz
• TTL compatible and optically isolated input
