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.
0.0 to 10.0 0.5Hz Programming
b2-02
DC Injection Braking
Current
DCInj Current
Selects the DC injection braking current as a percentage of the
Drive rated current.
0 to 100 50% Programming
b2-03
DC Injection Braking Time at
Start
DCInj Time @Start Sets the time length of DC injection braking at start in units of 1
second.
0.00 to
10.00
0.00sec Programming
b2-04
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
minimum 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.
0.00 to
10.00
0.00sec Programming
* If b1-13=1, this parameter instead selects whether the AUTO reference is retained as the new HAND reference (setting=0), or the drive will ramp from the AUTO
reference to the existing HAND reference (setting=1).
