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.

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
b3-01 0191H
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.

Delay Timers
b4-01 01A3H
Timer Function ON-
Delay Time
Delay-ON Timer Used in conjunction with a multi-function digital input and a multi-
function digital output. This sets the amount of time between when the
digital input is closed, and the digital output is energized.
