Key benefits - Prevents damage from end-of-travel conditions by using a reliable limit (stop) signal that halts movement during forward rotation. - Safe behavior persists even if the limit signal disappears; the motion remains stopped until the forward rotation signal is reactivated. - Self-locking PO versions provide latching forward motion with automatic stopping at designated end signals, enhancing control and predictability. - Flexible wiring and sensor compatibility simplify integration with existing control systems. What it is and how it works - Limit signal - The limit signal is also known as a stop signal. - It is a trigger type and level-activated signal. - If a short limit signal occurs during forward rotation, the movement stops. - Even if the limit signal disappears, it remains stopped. To move forward again, the forward rotation signal must be restarted. - PO versions (self-locking) - PO versions are self-locking. - When the external forward switch K1 is pressed, the motor rotates forward. - After the switch is released, the motor continues to rotate forward. - It stops only when it encounters the reverse turn signal K2 or the forward turn stop signal SW1. - Signal requirements and sensor compatibility - The signal is active low. - It can be a three-wire sensor (NPN-NO type). - The signals K1, K2, SW1, and SW2 comply with this specification. Compatibility and wiring details - Signal type: active low - Sensor options: three-wire NPN-NO type supported - Control inputs: K1, K2, SW1, SW2 are designed to comply with the active-low, three-wire sensor compatibility Use scenarios - Conveyor or feed line end travel - A limit signal detects the end of travel for a conveyor segment. If triggered, the line stops automatically. The signal’s persistence after triggering ensures a safe halt, and reactivation of the forward input resumes motion only when intended. - Automated gate or door control - The system uses K1 for forward motion and K2 or SW1 to stop. The self-locking PO option provides reliable forward motion until an end signal is reached, improving safety and timing in access control. - Small automation station with manual forward control - Operators press K1 to advance to a stop at the end signal. If the limit is reached or the end signal is activated, motion stops and requires re-engagement of forward input to proceed, reducing accidental overshoot. Technical notes - Limit signal applies as a stop condition during forward rotation - Restart of forward motion after a stop is initiated by reactivating the forward input - Compatible with standard control configurations using K1, K2, SW1, SW2 - Sensor wiring follows the active-low, three-wire NPN-NO convention This description maintains the original product specifications, models, and functional behavior while presenting clear, practical guidance for use, compatibility, and real-world applications.
