P, Ti and Td of PID controller do not match in setting properly. Reset PID
parameters.
9.3.8Inverter Stops Output While Motor Still Rotates

Insufficient DC Brake at Stop

DC brake torque at stop is too small. Please increase the set value of DC
brake current at stop (F04.21).

DC Brake Time at Stop is too short. Please increase DC brake time at stop
(F04.22). Generally speaking, increase DC brake current at stop first.
9.3.9Output Frequency Not As Per the Set Frequency

The set frequency exceeds the upper limit frequency.
If the set frequency exceeds the set value of the upper limit frequency, then output
frequency should be the upper limit frequency. Reset the set frequency within the upper
limit frequency; or check whether F00.16, F00.17 and F00.18 are appropriate.
