NX-CT features the Counter Comparison function with detection within 1 μs. It achieves high-speed, high-precision control through lightning-fast edge control, which processes signals instantly within the unit. It can reduce waste and loss on production sites caused by control delays, and contribute to production environments that can maximize added value.

Outputting a valve close signal at the timing of the count value reaching the target value often causes overfilling, as there is a delay until the valve closes completely.
NX-CT features the Advance Time setting that outputs the signal earlier by the delay time. It also monitors the filling speed internally and adjusts the closing time to prevent overfilling or underfilling caused by flow rate fluctuations.

During inline inspection, variations in conveyor speed prevent capturing an image so that it fits into the camera’s field of view, requiring workpieces to pause or slow down.
NX-CT’s Advance Time setting compensates for vision sensor delays and adjusts output timing in real time, ensuring correct positioning for image capture. This enables both high speed and high inspection quality.

Note: Although the above describes filling volume control, it also works for other applications including nonstop image inspection.

Transferring workpieces at shorter cycles than the PLC (several ms) generally overwrites the dimensional log and causes missing measurement data, preventing thorough pass/fail determination. NX-CT can capture external inputs at shorter cycles than the PLC and use the latch log mode to record up to 4,096 count values, ensuring acquisition of complete data utilized for pass/fail determination and improvement.

During DC motor shipping inspection, operational testing needs to be performed by simulating actual usage conditions. NX-CT features PWM Output for enabling/disabling output and making the duty cycle setting in 0.1% increments.
No special PWM output device is required to perform the inspection. This contributes to reduced design man-hours, space saving, and cost reduction.
