CL42T is a closed loop stepper driver designed to solve the loss of step problem in open loop stepper control systems, thus increase system reliability at minimal cost increase. It implements advanced control algorithm of based on its tens of years’ experience in stepper and servo controls. The CL42T is highly reliable and affordable and performs excellent in many industrial applications such as CNC, medical, electronics, packaging...The CL42T can power 2-phase NEMA11, 14 and 17 stepper motors with incremental encoders(Encoder resolution must be 1000-line). Compared with traditional open loop stepper systems, a CL42T adopted closed loop step system can eliminate potential loss of step, make real-time position error correction, and do not need torque reservation (100% torque implementation). Also it can power the driven stepper motor with reduced heating, lower noise, low vibration…
