brake is operated when this frequency is reached during deceleration.

Operation time setting (Pr. 11)
Use Pr. 11 to set the duration period the DC injection brake is applied.
When the motor does not stop due to large load moment (J), increasing the setting produces an

When Pr. 11 = 0s, the DC injection brake is not operated. (At a stop, the motor coasts.)
