• Driving Condition
- Maximum speed, Maximum torque
Maximum speed and torque of machine specification. If the
machine has some differential, use values of motor speed
and torque (not values of spindle).
- Spindle inertia
Actual value of spindle inertia. Use SI unit.
- Continuous load, Maximum load
Continuous and maximum load at cutting.
- Continuous working time
Continuous working time of machine for a day, including
intermittent intervals.
- Intermittent cutting
If the machine used for intermittent heavy cutting, check
Available. And write acceleration value. Estimated value
used for your machine designing is acceptable.
- Average power
Average power is calculated from the formula shown
below.

* If the average power exceeds the S1 continuous rated
power, it influences a motor life. Therefore, you had
better to define the average power within the S1
continuous rated power.
