Using the L Option 5-3
What Functions are Available? The L Option lets you choose a combination of the following
functions:
Control function Description
Accel/decel
rates (2)
These inputs let you select the acceleration and deceleration times the drive uses.
When single source inputs are used, Accel Time 2/Decel Time 2 are selected when this input is high (1) and Accel
Time 1/Decel Time 1 are selected when this input is low (0). 1 When multiple source inputs are used, a separate
Accel/Decel 1 and 2 are used. 2 
Digital potentiometer
(MOP) These inputs increase or decrease the drive commanded speed when MOP (Manually Operated Potentiometer) is
chosen as the speed command source. You can program the rate of increase or decrease.
Enable 3 Removing this input disables the inverter and the motor coasts to a stop.
Flux enable This input fluxes up the motor.
Fwd/Reverse
In single source modes, applying this input commands reverse direction and removing this input commands forward
direction. 1
In multiple source modes, a separate forward and reverse are used. 2
Jog
This input is a maintained (unlatched) start that follows the jog speed. When the jog input is removed, the motor stops
by a ramp, current limit, or coast stop based on how you set Logic Options (parameter 17).
Note: All starts must be low to jog.
Local control
Applying this input gives exclusive control of drive logic to the inputs at the L Option. No other devices may issue logic
commands (excluding stop) to the drive.
Not Ext Flt 4
This input is intended to fault the drive via external devices, such as motor thermoswitch and O.L. relays. Removing this
input faults the drive and the motor stops according to how the stop type 1 bit is set in Logic Options (parameter 17).
Process trim Applying this input enables the process trim function.
Ramp
Applying this input disables the ramp function. When the ramp function is disabled, the acceleration and deceleration
times are set to 0.
Reset Applying this input resets the drive.
Run forward 5
Applying this input issues both a start command and a direction command to the drive. Removing this input stops the
drive. The stop follows the stop type 1 specified in Logic Options (parameter 17).
Run reverse
5
Applying this input issues both a start command and a direction command to the drive. Removing this input stops the
drive. The stop follows the stop type 1 specified in Logic Options (parameter 17).
Speed selects (3) These inputs choose the speed command source for the drive.
Speed/torque
selections (3) These inputs take exclusive control of Spd/Trq Mode Sel (parameter 68). This lets you switch between the speed and
torque modes of the drive.
Start 1,2
Applying this input issues a start command for the drive to begin accelerating to the commanded speed. A stop
command is required to stop the drive. The stop follows the stop type in Logic Options.
Note: All jogs must be low to start. A transition from jog to start without a start transition is allowed (the drive is jogging,
you set a start, remove the jog, and the drive starts).
Not Stop, Clear
Fault
3
Removing this input issues a stop command for the drive. The drive stops according to the programmed stop mode
based on Logic Options (parameter 17) and the selected stop mode, if applicable. If the drive has faulted, removing this
input clears the fault if Clr Flt/Res Mask (parameter 127) is enabled.
Stop mode selects
(2)
Applying this input indicates that the L Option stop input follows stop type 2 in Logic Options (parameter 17). Removing
this input indicates that the L Option stop input follows stop type 1 in Logic Options.
Note: Stop mode only affects the L Option stop. Stops commanded from a terminal (such as a Human Interface
Module (HIM)) follow stop type 1 in Logic Options.
Speed Profiling
Mode 31 & 32 allow Speed Profiling to be accomplished through digital inputs. Refer to Chapter 9, Applications for more
information on this feature.
1 Available only with three-wire control, single source.
2 Available only with three-wire control, multi source.
3 Must be asserted for operation.
4 Must be applied for operation if L Option Mode (parameter 116) is not 1 or disable the fault in Fault Select 2 (parameter 22) and Warning
Select 2 (parameter 23).
5 Available only with two-wire control.
