Figure 7-11 Zero-speed monitoring, positioning window

The position controller monitors the standstill, positioning and following error.

Zero-speed monitoring is activated by binector inputs p2551 (setpoint stationary) and p2542 (zero-speed window). If the zero-speed window is not reached once the monitoring time (p2543) has lapsed, fault F07450 is triggered.

Positioning monitoring is activated via binector inputs p2551 (setpoint stationary), p2554 = "0" (travel command not active) and p2544 (positioning window). Once the monitoring time (p2545) has elapsed, the positioning window is checked once. If this is not reached, fault F07451 is triggered.

The standstill monitoring and the positioning monitoring can be de-activated using the value "0" in p2542 and p2544. The standstill window should be greater than or equal to the positioning window (p2542 ≥ p2544). The standstill monitoring time should be less than or equal to the positioning monitoring time (p2543 ≤ p2545).
