The CMD-4EX-SA-TBD has four built-in micro-stepping drivers, allowing the controller to directly drive 4 bipolar stepper motors. The CMD-4EX-SA-TBD uses a two-phase bipolar stepping motor driver that has the following features:


•PWM-controlled constant-current drive.

•Low on-resistance MOSFET output stage.

•Stepping resolutions of full, half, quarter, 1/8, 1/16, 1/32, 1/64, 1/128 step.

•High-efficiency motor current control mechanism (ADMD: Advanced Dynamic Mixed Decay)

•Built-in anti-stall architecture (AGC: Active Gain Control)

•Motor drive voltage 12 to 24Vdc

•Motor current 0.19A to 2.3A

•Multi error detection functions:

oThermal shutdown (TSD)

oOvercurrent (ISD)

oMotor load open (OPD)
