[Caution]
- Actual setting value is calculated by dividing the entry value by 0.9 and rounding up after the decimal points.
(e.g.: If an entry value is 80, setting value will be 89. And if an entry value is 20, setting value will be 23.) First,
make sure to let the customer know that the productivity will slow down slightly after making the setting. After
the customer accepts this, make the setting.
