Cooling Oil at Constant Capacity (%)

Cooling oil at a constant capacity (%)
With the above operation setting, the Oil Cooling Unit executes cooling operation according to the specified capacity
command (%). Oil temperature control is disabled.
The capacity setting range is 0 to 100%.
∗ The capacity (%) is an approximate index.
∗ When the capacity is set to "0"%, the compressor stops. (The pump and fan are running.)
∗ Even if the capacity command value is same, the actual cooling capacity varies depending on the room temperature and the inlet oil
temperature.
Caution
The oil temperature is not controlled in the operation mode: 9 and the main unit may be seriously damaged, use the product with extra care.
For example, if the cooling capability insufficient status such as 0% operation is caused at the maximum load or the cooling capability
excessive status like 100% operation is caused at low rotation, operating parts (such as the main shaft) may be damaged or burn out, or fire
may be caused in the worst case.
