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.
