SKU 6ES7551-1AB00-0AB0 Category Siemens Modules

The position detection module TMPosInput 2 is used for counting tasks as well as position detection.

In counting mode, the module detects high-speed signals with high frequencies and forwards the counter reading and the current speed to the control. The counter control ensures a precise counter result and rapid response in the system via digital input and output signals. Comprehensive parameterization options provide optimum adaptation to the task at hand and reduce control load.

For position detection, incremental encoders or SSI absolute encoders can be connected. Absolute encoders offer the advantage that the position of the axis is immediately available after switching on without the need for a reference run.
