User Manual of A90 Series Inverter

263

The adjustment parameters P, Ti and Td of the PID controller are not set correctly.

Please set the PID parameters again.

9.2.8 Motor rotation in the absence of inverter output



Insufficient DC braking for stop



The DC braking torque for stop is too small. Please increase the set value of the

DC braking current for stop (F04.21).



The DC braking time for stop is short. Please increase the set value of the DC

braking time for stop (F04.22). Under normal circumstances, please give priority

to increase in the DC braking current for stop.

9.2.9 Inconsistency between output frequency and set frequency



The set frequency exceeds the upper frequency limit.

When the set frequency exceeds the set value of the upper frequency limit, the output

frequency will be the upper frequency limit. Set the frequency again within the upper

frequency limit range; or check whether F00.16, F00.17 and F00.18 are appropriate.
