Monitor panel

Visualization of processing loadUse of the load meter enables setting of the optimal processing conditions.
Visualization of processing load Range of motor speedThe motor speed range is wide from 1,000 to 80,000 min-1, and the 3-digit digital display enables the speed to be set in 200 min-1 increments. There is no need to set the maximum motor speed as it automatically detects the connected motor.
