Module Description PWM DC motor speed controller and pulse generation module that provides control signals for the stepper drive. To control a stepper motor, a driver must be equipped. Key benefits Simple control platform: combines a controller, a stepper motor, and a DC power supply to form a straightforward motion control setup. Flexible input/output: supports measurement of input signals for PUL and a common cathode or common anode configuration (two ports), enabling easy integration with common stepper drivers. Versatile frequency options: offers multiple selectable frequency ranges to suit different stepping requirements and motor loads. Dual output modes: can generate both pulse signals and PWM signals, with mode selected by jumpers for easy without programming. Core capabilities Pulse generation and control: provides a PWM DC motor speed control function with pulse generation capabilities for stepper drive signals. Compatibility with stepper systems: designed to work with standard stepper drivers when paired with an appropriate DC power supply. Port monitoring: supports frequency measurement for PUL input and a twoport configuration for common cathode or common anode signals. Frequency signal options level range: 5.4 kHz to 160 kHz, selectable via jumpers. Medium level range: 540 Hz to 16.6 kHz, selectable via jumpers. Low level range: 80 Hz to 2.4 kHz, selectable via jumpers. PWM and mode selection Pulse signal output: can generate a pulse signal suitable for stepper control. PWM signal output: can generate PWM signals for speed control and smooth motor operation. Jumperselectable modes: switch between pulse and PWM output using jumpers to match application needs. Specifications and compatibility Function: PWM DC motor speed control with pulse generation for stepper drives. Compatibility: suitable for use with standard stepper motors and drivers when powered from an appropriate DC supply. Configuration: mode and frequency ranges are set via jumpers for simple, hardwarebased . Performance: supports a range of frequency options and dual output formats to accommodate varying motor requirements and load conditions. Use scenarios Simple CNC or positioning system: pair the controller with a stepper motor and a DC power supply to achieve basic, reliable positioning with selectable pulse or PWM control. Educational or hobby robotics: use the flexible frequency ranges and output modes to experiment with different stepping strategies and motor responses. Compact automation projects: integrate with small automation setups that require straightforward PWM or pulsebased motor control and easy signal measurement. Notes A compatible stepper driver is required to use the control signals produced by this module. Jumpers must be configured to select the desired output mode (pulse or PWM) and the desired frequency range.
