DC injection brake
Timing to stop or braking torque can be adjusted by applying DC injection brake at the time of stop-
ping motor.
By the DC injection brake operation, DC voltage is applied to the motor to prevent rotation of the mo-
tor shaft. The motor shaft will not return to its original position when it is rotated due to external force.
Initial value for the FR-F820-00340(7.5K) or lower and FR-F840-00170(7.5K) or lower.
Initial values for the FR-F820-00490(11K) to FR-F820-02330(55K), FR-F840-00250(11K) to FR-F840-
01160(55K).
Initial value for the FR-F820-03160(75K) or higher and FR-F840-01800(75K) or higher.
Setting of operating frequency (Pr. 10)
●
By setting the frequency to operate the DC injection brake to Pr. 10 "DC injection brake operation
frequency", the DC injection brake will operate when it reaches this frequency at the time of
deceleration.
●
When Pr. 10 = "9999", DC injection brake will start when the frequency reaches Pr. 13 "Starting
frequency".
●
The DC injection brake operation frequency depends on the stopping method.
●
DC injection brake operation frequency will be fixed to 0 Hz at the time of PM motor control.
