1. KL-5080D4

KL-5080D4 is a closed loop stepper drive. When used to drive a 2-phase stepper motor in frame sizes NEMA 8, 17, 23, or 24 with incremental rotary encoder, it can close the position loop between the motor and drive and therefore eliminate the loss of step problem in an open loop system.

Feature of KL-5080D4:

  • Step & direction or CW/CCW control modes
  • Supply voltage of 20-50 VDC, maximum output current of 8.0A
  • Powering 2-phase stepper motors of NEMA 8, 11, 14, 17, 23, and 24
  • Fault output, brake control, or in-position output.
  • No lose of steps for closed position loop
  • No tuning
  • No overshooting
  • No torque margin
  • Reduced motor heating and more efficient
  • Smooth motion and super-low motor noise
  • CE certified and RoHS compliant


The KL-5080D4 closed loop stepper drive is suggested to be implemented along with a compatible 2-phase stepper motor (usually NEMA 17, 23 and 24) with 1000-line encoder. That closed stepper system can be used to upgrade open loop stepper systems or replace some servo systems, especially in many small to median speed applications such as CNC routers, CNC mills, CNC laser cutters, CNC plasmas, lab automation instruments, electronic equipment, small packaging machines, etc.

2. NEMA23 KL23-31N-1000

The NEMA23 KL23-31N-1000 motor is a 2 phase stepper motor with 3.1 N.m (439 oz-in) holding torque and integrated with a 1,000 line (4,000 counts/revolution) differential ended rotary encoder. Build with high quality materials including bearings and shaft made by Japanese manufacturers, this closed loop stepper motor can be adopted in many industrial applications with excellence performance such as high precision, low motor heating, and low vibration.
