Setting 14: Fault Reset
When the drive detects a fault condition, the fault output contact closes, the drive output shuts off, and the motor coasts to
stop (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). After removing the Run
command, clear the fault either by pressing the RESET key on the digital operator or closing a digital input configured as a
Fault Reset (H1-oo = 14).
Note: Remove the Run command prior to resetting a fault. Fault Reset commands are ignored while the Run command is present.
Settings 15 and 17: Fast Stop (N.O., N.C.)
The Fast Stop function operates similar to an emergency stop input to the drive. If a Fast Stop command is input while the
drive is running, the drive decelerates to a stop in the deceleration time set to C1-09. The drive can only be restarted after
bringing the drive to a complete stop, turning off the Fast Stop input, and switching off the Run command.
• To trigger the Fast Stop function with an N.O. switch, set H1-oo = 15.
• To trigger the Fast Stop function with an N.C. switch, set H1-oo = 17.
Figure 4.36 shows an operation example of Fast Stop.

NOTICE: Rapid deceleration can trigger an overvoltage fault. When faulted, the drive output shuts off, and the motor coasts. To avoid this
uncontrolled motor state and to ensure that the motor stops quickly and safely, set an appropriate Fast Stop time to C1-09.
Setting 18: Timer Function Input
This setting configures a digital input terminal as the input for the timer function. Use this setting combination with the timer
function output (H2-oo = 12).
Setting 19: PID Disable
Close a digital input to indefinitely disable the PID function. When the input is released, the drive resumes PID operation.
Setting 1B: Program Lockout
Parameter values cannot be changed when an input is programmed for Program Lockout and the input is open. It is still possible,
however, to view and monitor parameter settings.
Setting 1E: Reference Sample Hold
This function allows the user to sample an analog frequency reference signal being input to terminal A1, A2, or A3 and hold
the frequency reference at the sampled level. When the Analog Frequency Reference Sample/Hold function is held for at least
100 ms, the drive reads the analog input and changes the frequency reference to the newly sampled speed as illustrated in
Figure 4.37 .
When the power is shut off and the sampled analog frequency reference is cleared, the frequency reference is reset to 0.
