03 LS Lockout
7 - PARAMETER DESCRIPTION
LCD Display
Description This parameter allows you to select whether the drive will automatically start when line power is applied
while a Run command is active.
Parameter Value Description
LS Lockout (Default)
Line Start Lock-Out. The drive will not automatically start when line power is applied and a Run
command is active. Instead, the run command must be removed and a new run command given.
Auto Start
The drive will automatically start when line power is applied and a run command is active on the
terminal strip.
LSL w/FLY
This setting has both LS Lockout and Catch on the Fly enabled at the same time. When restarting, the
drive will try to “catch” the motor and match its speed.
z NOTE: See AFN 18 - Catch Mode on page 116.
Auto w/FLY
This setting has both Auto-Start and Catch on the Fly enabled at the same time. When restarting,
the drive will try to “catch” the motor and match its speed.
z NOTE: See AFN 18 - Catch Mode on page 116.
Torque Curve FUN 02
FUN: Torque Curve
02 Linear Fxd
LCD Display
Description This parameter selects the control algorithms used by the RSi S4 drive. The V/Hz Characteristic Selection
parameter determines the characteristic of the V/Hz curve and whether any boost will be applied at tarting.
The amount of boost may be automatically determined or set with parameters AFN 07 - V-Boost Conf on
page 112.
z NOTE: Vector control requires careful programming of motor parameters.
Parameter Value Description
Linear Auto
V/Hz curve with auto-boost. This is typically used for constant torque applications; however, do not use
it for multi-motor applications. The amount of boost applied varies from zero to the value of parameter
AFN 07 - V-Boost Conf - on page 112 and is calculated by the drive based on the load.
Linear Fxd (Default)
V/Hz curve with the amount of boost xed at the value set in parameter AFN 07 - V-Boost Conf on
page 112. Curve designed for constant torque applications.
Pump Fxd
V/Hz curve with the amount of boost xed at the value set in parameter AFN 07 - V-Boost Conf on
page 112. Curve designed for pump applications
Fan Fxd
V/Hz curve with the amount of boost xed at the value set in parameter AFN 07 - V-Boost Conf on
page 112. Curve designed for fan applications.
Linear 2pc
Uses parameters AFN 08 - Bst. Trp Freq on page 113 and AFN 09 - Bst. Tpr Vlt. These parameters
are used to dene a midpoint through which the V/Hz curve passes so a custom curve may be created
for special motor applications.
Vector
Activates the sensorless vector algorithm for high torque/low speed operation. A vector-duty motor
should be used for this mode of operation. Vector mode does not use either of the boost parameters.
z NOTE: See AFN 10, 11, 12, 13 and 14 starting on page 114.
z NOTE: When set to “Vector”, the drive must rst perform an autotune on the motor to calculate
the motor RS. See page 151 for more information on autotuning.
