DC Injection Braking

Current

DCInj Current

Selects the DC injection braking current as a percentage of the drive

rated current.

DCInj Time @ Start

Sets the time length of DC injection braking at start in units of 1

second.

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

b3-01 0191

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.

SpdSrch Current

Used only when b3-01 = 3. Sets the speed search operation current as a

percentage of drive rated current.
