Creep speed is a very slow, precise speed used for the final approach to a target position or during referencing, ensuring accuracy and preventing overshoot.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCan I use both incremental and absolute encoders?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the module supports both. Incremental encoders are common for relative positioning. Absolute SSI encoders provide a unique position value on power-up, eliminating the need for a reference run after each startup.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat are \"reference cams\" and \"reversing cams\"?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eReference cams are physical switches or sensor signals used to establish a known reference point (home position) for the axis. Reversing cams act as hardware limit switches to immediately stop motion if the software limits are passed, providing a safety backup.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow is the motion profile programmed?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYou do not write traditional motion code. Using the configuration software in STEP 7, you define target positions, speeds, and acceleration ramps. The module then executes these profiles autonomously, reporting status back to the main CPU.\u003c\/p\u003e\n\u003cp\u003e© 2026 Ubest Automation Limited.
