4.8 Operating Using Speed Control with an Internally Set Speed
The function of internally set speed selection allows speed control operation by externally selecting an input signal from
among seven servomotor speed setting made in advance with parameters in the servo drive. The speed control
operations within the three settings are valid. There is no need for an external speed or pulse generator.
