Intelligent dual-mode control: two fully automatic operating modes plus manual control options give precise, repeatable control over forward and reverse motion without constant operator adjustment. Clear LCD feedback: backlit LCD displays the current forward-rotation percentage and working time information so operators can see speed and runtime at a glance for consistent results. Adjustable acceleration, deceleration and delay: set slow (ramp) and delay times with configurable upper-limit values to tailor start/stop behavior and avoid abrupt motion. Built-in timer for direction and tapping control: the integrated timing function switches forward/reverse and controls acceleration/deceleration and tapping delays, addressing shortcomings of conventional potentiometer-based controls. Why you need this product Consistent, repeatable motion control reduces rework and variability compared with manual potentiometer adjustment. Digital display and upper-limit settings make it faster to set up and safer to run, especially for repetitive or batch operations. The timer-driven direction and tapping control eliminates the need for constant operator intervention and improves process reliability. Key attributes and performance Function: digital controller providing dual automatic modes, manual control, timed forward/reverse switching, and adjustable acceleration/deceleration and delay. Feedback: backlit LCD shows forward-rotation percentage and working time status for quick verification. Control limits: supports upper-limit settings for slow and delay times to prevent excessive ramp or pause durations. Design focus: replaces traditional potentiometer-based timing with programmable, timer-controlled switching to improve precision and reduce operator tuning. Applications / use scenarios Precision tapping and screwdriving: set acceleration, delay, and forward/reverse timing to perform repeatable screw insertion and reversal cycles without manual trimming. Small assembly automation: integrate into pick-and-place or assembly fixtures that require reliable, timed forward/back motion for repeatable part handling. Test benches and prototyping: use the controller to run repeatable forward/reverse cycles with controlled ramping and delay for motor or mechanism testing. What it solves Eliminates the variability and manual tuning associated with conventional potentiometers. Reduces setup time by providing visible speed/ time feedback and configurable limits. Improves repeatability and process control for applications requiring precise forward/reverse cycling and timed tapping. Operation notes Use the LCD readout to confirm forward-rotation percentage and working time during setup and operation. Configure slow (ramp) and delay time upper limits to match your process requirements and avoid overly long transitions. Employ the timer-driven switching for reliable, repeatable forward/reverse and tapping sequences without mechanical adjustment. This product is intended for applications that require digital timing and repeatable control of forward and reverse motion, precise ramping and delay adjustments, and clear on-device feedback to reduce operator intervention and improve process consistency.
