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
Time at Stop
DCInj Time @ Stop
When b1-03 = 2 actual DC Injection time is calculated as follows:
b2-04 x 10 x 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.

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).

Speed Search Selection
SpdSrch at Start
Enables/disables and selects the speed search function at start.
0: SpdsrchF Disable - Speed search at start is disabled (estimated speed
method is used at other times)
1: SpdsrchF Enable - Speed search is enabled (estimated speed method)
2: SpdsrchI Disable - Speed search at start is disabled (current detection
method is used at other times)
3: SpdscrhI Enable - Speed search is enabled (current detection method)
Estimated Speed Method: Actual motor speed and direction is estimated,
then the motor is ramped from that speed to the commanded speed.
Current Detection Method: Current level is monitored while output
frequency is ramped down.
