Electroplating driving PLC control ladder diagram

Design of PLC control program for electroplating special crane. According to the control process of electroplating special crane and the I/O address allocation of PLC,
a PLC ladder diagram program can be designed. Part of the ladder diagram is shown in Figure 26-36.
    The ladder diagram shown in the figure is composed of stop, ascend, descend, forward, retreat, ascending braking, descending braking, forward braking and reverse braking
. According to the control requirements of electroplating-specific driving, in addition to meeting the control requirements, each link also fully considers
the interlocking between each link, including the interlocking between the four links of ascending, descending, forward, and retreat, as well as the interlocking between ascending and descending.
Interlocking between ascending braking, descending and descending braking, forward and forward braking, reverse and reverse braking, etc. to ensure the safety of system operation.
    (4) Conclusion Transforming manually operated semi-automatic electric driving to automatic control can greatly improve production efficiency. Choosing PLC as the controller
for the automatic operation of electric bicycles can not only easily realize various control functions, but also adapt to the harsh working environment in which the bicycle is located, without taking too many measures on the hardware.     This example uses PLC to automatically control a special electroplating vehicle, which simplifies the hardware wiring of the electrical control system , reduces the size of the controller , and improves the flexibility of the control system . At the same time, PLC's effective and complete self-diagnosis and self-protection capabilities can enhance the system's anti-interference ability and improve system reliability.
