The high-speed input function of the GT3U series PLC has the following key points:
High-speed input function
Supported input channels:
The GT3U series supports multiple high-speed input channels, such as C235 to C255, and the use of specific channels depends on the model.
Input mode:
Supports single-phase and dual-phase input modes, which can be selected as needed.
Maximum response frequency:
The maximum response frequency of the high-speed counter is 100KHz (depending on the input type and settings).
Multiplication setting:
The user can set the multiplication, supporting 2x and 4x counting to increase the resolution of the input signal.
Pulse capture function:
Supports pulse capture, which can capture the changes of pulse signals in real time for precise counting and position control.
Interrupt input:
High-speed input can be configured as interrupt input for faster response and processing.
Precautions
Make sure the input channel settings match the sensor or encoder used.
When using the high-speed input function, pay attention to the stability of the signal to avoid miscounting.
For detailed configuration and usage methods, please refer to the relevant chapters in the PLC manual.
