Note 1: These functions (from F1119 to F1123) enable during V/f control mode (F1001=1 or 40). When the inverter run
speed control mode (F1001=2 or 3), these functions can set by F6007 and F6008.
Note 2: During DC braking, the motor has possibility over heat, because the motor is very low speed and self cooling
effect is down. Therefore DC braking force set small value, keeping motor cool level. We recommend using a
thermal relay.
Note 3: If DC braking force set big and braking force don’t change, then the motor becomes over current by something
reason and the inverter is protected by current limiter.
Note 4: Acceleration DC braking time set by F1113 and acceleration DC braking force set by F1114.
