User Manual of EM760 High-Performance Inverter * DC braking is started as shown in the figure below. Fig. 6-13 Process of starting DC braking When multiple motors are driven by a single inverter, this function can be applied. The inverter will start running after the magnetic field is established according to the set pre- excitation current F04.06 and the set pre-excitation time F04.07 is up. Ifthe pre-excitation time is set to 0, the inverter will be started directly without pre-excitation. The pre-excitation current F04.06 is the percentage relative to the rated no-load current of the motor.
