The smaller value is enabled, the speed limit input from V-REF or the Pn406 (speed limit during torque control) when
Pn005=H.

·
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.
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.
