DC Braking

b2-01

DC Injection Braking Start
Frequency
DCInj Start Freq

Sets the frequency at which DC injection braking starts when ramp
to stop (b1-03 = 0) is selected. If b2-01< E1-09, DC Injection
braking starts at E1-09.

DC Injection Braking
Current
DCInj Current

Selects the DC injection braking current as a percentage of the
Drive rated current.

DCInj Time @ Start

Sets the time length of DC injection braking at start in units of 1
second.

DC Injection Braking Time at
Stop
DCInj Time @ Stop

When b1-03 = 2 actual DC Injection time is calculated as follows:
b2-04 * 10 * Output Frequency / E1-04. When b1-03 = 0, this
parameter determines the amount of time DC Injection is applied to
the motor at the end of the decel ramp. This should be set to a min-
imum of 0.50 seconds when using HSB. This will activate DC
injection during the final portion of HSB and help ensure that the
motor stops completely.

Motor Pre-Heat Current
Preheat Current

Motor Pre-heat current in % of Drive rated current. This is used to
keep the motor warm to prevent condensation and is used in
conjunction with a digital input (data = 60).
