Programmable Stepper Module Control



  • Can control up to two axes suitable for controlling stepper/servo motors
  • Addressable up to SIX AXIS
  • LED indicators for I/Os
  • Three different types of speed control methods for the most flexible stepper motor controlling: 
    -- Trapezoidal profile motions
    -- S-curve profile motions
    -- Adjustable curve profile motions
  • 66.67 KPPS maximum pulse output (Line Driver 400mA or Differential Output) 
  • Adjustable speed during operation 
  • Easy removable screw terminal connections
  • Plug-in Module for MP200 Operator /Smart Controller
  • Excellent for Cost sensitive Motion Control Applications with the need of precision
  • Dimensions: 7.25" x 5.00"


Speed control method Trapezoidal profile motions, S-curve profile motions, 
Adjustable curve profile motions. 
* Software selectable at the initialization
Acceleration/Deceleration pulse rate 8 pulses to 65,535 pulses
Number of speed adjustment stages Maximum 96 stages
Pulse output Frequency 31 PPS to 66.67 KPPS (Normal speed mode), 
8 PPS to 16.67 KPPS (1/4 speed mode), 
2 PPS to 4.17 KPPS (1/16 speed mode).
Method Single phase pulse output method with direction signal
Width/Type Duty ratio 50%, Line Driver, Differential Outputs for both Pulse and Direction outputs
Maximum number of output pulses +/- 16,777,215 pulses
