The motor rotates but the speed does not change.

The change in the rotation speed of the motor is
also small in the following cases.

— "F01 "Frequency command 1" and C30

"Frequency command 2" are set at "3" and a
signal is input from both of control terminals
12 and C1, and there is no change in the 
sum of them.

— The load is excessively large and the torque

limit and current limit functions are activated.
