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 three servomotor speed setting made in advance with parameters in the
servodrive. The speed control operations within the three settings are valid. There is no need for an
external speed or pulse generator.
4.8.1 Setting Parameters
(Note):The servomotor’s maximum speed will be used whenever a speed setting for the Pn301
～
Pn303
exceeds the maximum speed.
The setting in Pn300 determines the voltage level to be input as the limit value. Polarity has no effect.

Set the voltage level for the speed that is to be externally limited during torque control.
With Pn300=150(factory setting) and 6V input from V-REF(CN1-1,2), the actual servomotor speed is
limited to the rated speed of the servomotor used.
