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

Standstill (zero-speed) monitoring
Zero-speed monitoring is activated via 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.
Zero-speed monitoring is deactivated with value "0" in p2542. The standstill window should
be larger than or equal to the positioning window (p2542 ≥ p2544). The standstill monitoring
time should be less than or equal to the position monitoring time (p2543 ≤ p2545).
Position monitoring
Position monitoring is activated using 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.
Positioning monitoring can be deactivated with the value "0" in p2544. The standstill window
should be larger than or equal to the positioning window (p2542 ≥ p2544). The standstill
monitoring time should be less than or equal to the position monitoring time
(p2543 ≤ p2545).
