Parameter Motor brake and stop operation
FR-E700 SC EC/ENE 6 - 101
Operation frequency setting (Pr. 10)
When the frequency at which the DC injection brake operates is set to Pr. 10, the DC injection 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
effect.
When Pr. 11 = 0 s, the DC injection brake is not operated. (At a stop, the motor coasts.)
