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.
