Functions
Output Voltage Gain
•Changes the Inverter output voltage in percentage terms based on the AVR voltage selection
[A082] as 100%.
•The Inverter cannot output voltage beyond that of the incoming voltage.
DC Injection Braking (DB)
This function securely stops the motor rotation during deceleration.
•Two methods are available for DC injection braking: One is the external method via the multi-
function input (external DC injection braking); the other is the internal method performed
automatically to stop the motor (internal DC injection braking).
•Below are operation types:
Edge operation: DB operates during the specified time period from the DB signal input.
Level operation: DB operates while a signal is being input.
Frequency control mode: DB operates when the frequency reaches the specified level during
operation.
•If DC injection braking operates at a high motor speed, an overcurrent trip (E01 to E04) or overload
trip (E05) may occur. For internal DC injection braking, the following adjustment may help you
avoid such a situation:
Lower the DC injection braking frequency (A052).
Increase the DC injection braking delay time (A053)
For external DC injection braking via the multi-function input, use the external DC injection braking
terminal (along with deceleration stop).
