4-2 Function Mode Output voltage (V) V7 Select the voltage or motor voltage available for output. V6 0 f6 f7 Output frequency (Hz) Output Voltage Gain 4 •Changes the Inverter output voltage, based on the voltage selected in AVR voltage selection A082 as 100%. •You can avoid motor hunting by reducing the output voltage gain. Functions Motor voltage selection (100%) (A082) A045 Base frequency (A003/A203/A303) Max. frequency (A004/A204/A304) DC Injection Braking •DC injection braking is applied to the motor depending on the motor load. •Two methods are available for DC injection braking:
One is the external method via the multi- function input terminal; the other is the internal method performed automatically to start/stop the motor. Even if DC injection braking is used, however, the motor may not stop depending on the moment of inertia of the motor load. 4-24 Parameter No. Function name Data Default setting Unit A045 Output voltage gain 20. to 100. 100. % Related functions A082 Parameter No. Function name Data Default setting Unit A051 DC injection braking selection 00: Disabled 01: Enabled 02: Frequency control [A052 set value] (Enabled only at the set frequency.) 00 A052 DC injection braking frequency 0.0 to 400 0.5 Hz
