Functions
Output Voltage Gain
•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.
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.
