* If b1-13=1, this parameter instead selects whether the AUTO reference is retained as the new HAND reference (setting=0), or the drive will ramp from the AUTO
reference to the existing HAND reference (setting=1).

Table A.1 Parameter List (Continued)
Description
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).
Sets the DC preheat current for multi-function output setting 80
(Motor Preheat 2) as a percentage of Motor Rated Current (E2-01).
Speed Search
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
Delay Timers
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.
PI Control
This parameter enables / disables the closed loop (PI) controller.
0: Disabled
1: Enabled (commanded speed becomes PI setpoint)
3: Fref+PI
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.
Sets the amount of offset of the output of the PI controller. Set as a %
of fmax.
The PI Offset Adjustment parameter has two different uses.
Parameter b5-07 serves different functions depending on whether it is
used on a standard PI loop or a Differential PI loop.
1: Parameter b5-07 causes an offset to be applied to the output of the
PI function in a non-Differential PI loop. Every time the PI output
is updated, the offset is summed with the PI output. This can be
used to artificially kick-start a slow starting PI loop.
2: If the Drive is configured for Differential PI Regulation
(H3-09=16), then the PI Offset is the targeted maintained differen-
tial between the signal measured on analog input A1 and the signal
measured on analog input A2.
