The stranding machine reports a cradle shaking alarm if the cradle shaking detection signal is abnormal. If such an alarm is reported, check the signal of the cradle shaking detection sensor first. If the indicator is on, a fault occurs. If the indicator is off, the signal is normal. If a fault occurs, check the position of the reflective board and adjust its angle until the alarm is cleared.

Slip control is implemented by detecting the pulse signals of the drawing linear speed and the winding linear speed. It can quickly and accurately adjust the winding speed to maintain the slip within a certain range, reduce the failure rate, and improve the wire drawing quality. Slip control features high control precision, constant tension, and small and stable slip, delivering good wire quality. Compared with oscillating bar control, slip control has lower costs because it does not need oscillating bars, guide wheels, and potentiometers. Therefore, slop control (also called oscillating bar-free control) is mainly applied to ultra-fine wires and wires that have high quality requirements.

Possible causes for this problem are as follows: The emergency stop signal has a short circuit or open circuit fault. Parameters are set incorrectly. Factory settings are not restored before commissioning. To rectify this fault, check the signal cable between PLC-X20/PLC-Y15 and the all-in-one machine HDI2, and replace the cable if necessary.
