Description
Speed Search
Enables/disables and selects the speed search function at start.
0: Speed Estimation Speed Search Disable - Speed search at
start is disabled (however the estimated speed method is used
for multi-function input, power loss ridethru, auto fault retry)
1: Speed Estimation Speed Search Enable - The speed estimation
method of speed search is enabled at run command.
2: Current Detection Speed Search Disable - Speed search at
start is disabled (however the current detection method is used
for multi-function input, power loss ride through, auto fault retry)
3: Current Detection Speed Search Enable - The current detection
method of speed search is enabled at run command.
Speed Estimation Method: Motor speed and direction are
measured using residual motor flux.
Current Detection Method: Motor speed is measured using current
feedback levels (unidirectional only).
Used only when b3-01 = 2 or 3. Sets the speed search operation
current as a percentage of Drive rated current.
Used only when b3-01 = 2 or 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.
Sets the gain for the frequency at which the Drive starts speed
estimation speed search. Use only when b3-01 = 0 or 1.
This parameter enables the Drive to detect the direction of rotation
of the motor during speed search.
0: Disable - Drive uses frequency reference direction.
1: Enable - Drive uses detected direction
Delay Timers
Used in conjunction with a multi-function digital input and a multi-
function digital output programmed for the timer function. 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 programmed for the timer function. This
sets the amount of time the output stays energized after the digital
input is opened.
PID Control
This parameter determines the function of the PID control.
0: Disabled
1: D = Feedback
2: D = Feed-Forward
3: Freq. Ref. + PID output (D = Feedback)
4: Freq. Ref. + PID output (D = Feed-Forward)
Sets the proportional gain of the PID controller.
Sets the integral time for the PID controller. A setting of zero
disables integral control.
Sets the maximum output possible from the integrator. Set as a
percentage (%) of maximum frequency.
Sets D control derivative time. A setting of 0.00 disables
derivative control.
Sets the maximum output possible from the entire PID controller.
Set as a percentage (%) of maximum frequency.
