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.
Selects the DC injection braking current as a percentage of the drive rated
current.
Sets the time length of DC injection braking at start in units of 1 second.
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 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).
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.
Used only when b3-01 = 3. Sets the speed search operation current as a
percentage of drive rated current.
Used only when b3-01 = 3. Sets the deceleration time during speed search.
Delays the speed search operation after a momentary power loss to allow
time for an external output contactor to re-energize.
0: Disabled
1: Enabled
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.
Used in conjunction with a multi-function digital input and a multi-
function digital output. This sets the amount of time the output stays
energized after the digital input is opened.
This parameter enable /disables the closed loop (PI) controller.
0: Disabled
1: Enabled (commanded speed becomes PI setpoint)
2: Enabled - 2 Zone (dual zone PI enabled)
Sets the proportional gain of the PI controller.
Sets the integral time for the PI controller. A setting of zero disables
integral control.
Sets the maximum output possible from the integrator. Set as a % of fmax.
Sets the maximum output possible from the entire PI controller. Set as a %
of fmax.
