DC Injection
With decel to stop enabled (B03-03=0), upon removal of the run command, the IMPULSE
®
•G+ and
VG+ Series 4 drive controls motor deceleration according to the Decel Time setting (B05-02), until
output frequency reaches the DC Injection Braking Start Frequency (D01-01 setting). Then the
IMPULSE
®
•G+ and VG+ Series 4 frequency output is turned off and DC injection current is applied
to the motor. The effective DC injection time and current should be set to provide adequate stopping
without excessive motor heating. The DC injection voltage is determined by the DC injection braking
current and motor impedance.
