Drive Delay Time Setting
Wait to Run Time
After a run command, drive output will start after this delay time. 0 to 600 0sec Programming
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.

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 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).
