In the following cases, changing the motor speed is also restricted:

Signals are input from control terminals both 12 and C1 when “F01 Frequency command 1”and “C30 Frequency command 2” are set to 3, and there is no significant change in the added value

The load is excessive, and the torque limiting and current limiting functions are activated
