Built-in CPU positioning control function<sup>Positioning</sup>
<sup>Contador de alta velocidad</sup>
Función de posicionamiento
The built-in positioning function has a start time of just 30 µs with a maximum high speed output of 200K pulses per second.
Furthermore, it supports S-curve acceleration and deceleration for applications that require minimal machine vibration.
High-speed counter function
Two channels support the high speed counting function. The differential line driver inputs support counting speeds up to 200K pulses per second.
Make highly accurate measurements with a resolution of 5 µs<sup>High-Speed Counter</sup>
Using pulse measurement mode, where the input signal ON/OFF time is 200 µs or greater, highly accurate measurements in units of 5 µs or greater are possible.
For example it is possible to calculate length by knowing the "work object passing speed" and measuring the ON time of the sensor.
High precision PWM control up to 200 kHz<sup>High-Speed Counter</sup>
Using the pulse width modulation control function of the high speed outputs, cycle times as fast as 5 µs can be created.
Simply input the ON time and cycle time to drive a wide range of devices from lighting dimmer control, motors, and heaters to precision inspection equipment requiring high resolution performance.
■ Lighting dimmer control using PWM output
- *1.In cases where the first six digits of the serial number are "120722" or later. Previous serial numbers of the CPU module are applied to 100 mA.
| Setting item | Rango de configuración | Descripción |
|---|---|---|
| PWM output ON time*2 | 0 or 10...10000000*2 (0,1 µs) | Set the ON time of output pulse |
| PWM output cycle time*2 | 50...10000000*2 (0,1 µs) | Set the cycle time of output pulse |
- *2.The PWM output ON time must be ≤ than PWM output cycle time.
Guaranteed input pulse detection<sup>Pulse Catch</sup>
Typical programmable controller input devices are unable to detect pulse signals whose ON time is shorter than the scan time or do not occur during I/O refresh periods. The pulse catch function allows these signals to be reliably detected and passed to the sequence program. This function is different from the interrupt input function in that it does not require any special programming. Pulse catch inputs may be used in programs exactly the same as traditional input (X) signals.
CPU with built-in CC-Link network connectivity<sup>L26CPU-(P)BT</sup>
L Series CC-Link ready CPUs are compatible with the latest generation of CC-Link devices and support connections with over 1.000 different product types. Without adding a module, these CPUs can perform high-speed communication with a maximum of 128 words*3 between a master station and a local station. CC-Link is the dominate FA network standard in Asia and continues to gain support worldwide.
- *3.When the number of occupied stations is 4 and the extended cyclic setting is octuple in the Remote net Ver.2 mode.
