- Position loop gain
Fill in this blank with a value which is considered to be settable
judging it from the inertia value based on experiences.
Since this value is not always applicable due to rigidity, damping
constant, and other factors of the machine tool, it is usually
determined on the actual machine tool. If the position sensor is
mounted outside the motor, this value is affected by the machine tool
rigidity, backlash amount, and friction torque value. Enter these
values without fail.
- Dynamic brake stop distance
Enter the coasting distance when an abnormality occurs and the
machine tool is stopped by dynamic braking with both ends of the
motor power line shorted.
