Three design schemes for risk-free energy saving in automobile automatic production

By "visualizing" the power consumption of the entire production line, it helps realize risk-free power saving.

Three design schemes for risk-free energy saving in automobile automatic production

Solution 1: Use the power measurement unit to instantly detect the section where power abnormality has occurred


The power measurement unit can instantly detect the production line section where the power supply is abnormal, so it can prevent the outflow of the post process of the abnormal quality car and the line output before the shipment, and reduce unnecessary costs.
It can detect the symptoms of motor abnormalities (bearing life, ageing, burnt, etc.) before failure, and implement countermeasures such as overhaul and repair.
You can know where, when, and during what period the power supply abnormality occurred, and it can be rejected in the middle of the production line. Therefore, it does not flow out to the subsequent process/shipping, and it is possible to take measures against defective products without unnecessary effort and cost.

Solution 2 Use programmable controller type power measurement unit to save space/save wiring


The company's power measurement unit is a programmable controller type, so it can be directly connected to the empty slot of the base unit.
There is no need to use the space required for external measurement equipment and to make communication units, cables, and communication programs, so space/wiring can be saved.
Power measurement unit (QE81WH)
·After using the empty slot of the base unit, the power measuring equipment can be imported without affecting the equipment configuration in the control panel.
· There is no need to make communication units, communication cables, and communication programs. Costs can be saved by saving wiring and reducing engineering workload.
·Single-line buffer memory automatically collects measurement data at a speed of 250ms and multi-line buffer memory at a speed of 500ms, so detailed cost unit management can be realized.
·It is possible to simply display the cost unit and the movement of the load with a graph on the display (GOT) installed in the control panel of the manufacturing site.

Solution 3 Prevent sudden failures by monitoring the current (or power) for a long time


Through the long-term monitoring function in the power measurement unit, the abnormal signs of energy are detected, the abnormality is grasped before the failure occurs, and the maintenance/refurbishment of the equipment can prevent the production line stop and accidents caused by sudden failures in advance.
The FREQROL-A701 series equipped with a power regeneration function has a huge braking capacity and is the most suitable inverter for lifting applications and production line control.
Renewable energy will return to the power source, so it generates less heat than the resistor braking method and has a more energy-saving effect.
It adopts the integrated structure of the inverter and the power regeneration converter. Compared with the separate placement of the traditional general-purpose converter, the main line wiring number is about 40%, and the installation area is about 60%, which is 7.5K, which can achieve savings in distribution. Line, space-saving effect.
