GB - 15Technical Data of the 400 V ClassThe technical data are for 2/4-pole standard motors. With other pole numbers the invertermust be dimensioned onto the motor rated current. Contact KEB for special or medium fre-quency motors.No braking resistor may be connected for control type "Basic" at an input rated volt-age of 480 Vac. The response threshold of the braking transistsor (Pn.69) for all othercontrols without safety technology (A, E, G, H, M) must be adjusted at least to 770 Vdc(see annex D).2.4 DC supply2.4.1 Calculation of the DC input currentThe DC input current of the inverter is basically determined by the used motor. The data canbe taken from the motor name plate.230V class :IDC = √3 • rated motor voltage • rated motor current • Motor cos φ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––DC voltage (310 V)400V class :IDC = √3 • rated motor voltage • rated motor current • Motor cos φ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––DC voltage (540 V)The DC input peak current is determined by the operating range.• If you accelerate on the hardware current limit, the short-time current limit of the in-verter must be used in the formula above (instead of the rated motor current).• If the motor in normal operation is never stressed with rated torque, it can be calculatedwith the real motor current.2.4.2 Internal input circuitThe COMBIVERT F5/F6 in D housing corresponds to the inverter type A1. Pay attention tothe inverter type in DC interconnection and in operation at regenerative units.Inverter type for COMBIVERT F5/F6 in D housing: A1+++--L1L2L3
