Setting 14: Fault Reset
Whenever the drive detects a fault condition, the fault output contact will close and the
drive’s output will shut off. The motor then coasts to stop (specific stopping methods can be
selected for some faults such as L1-04 for motor overheat). Once the Run command is
removed, the fault can be cleared by either the RESET key on the digital operator or by
closing a digital input configured as a Fault Reset (H1- = 14).
Note: Fault Reset commands are ignored as long as the Run command is present. To reset a fault, first
remove the Run command.
Setting 15/17: Fast Stop (N.O./N.C.)
The Fast Stop function operates much like an emergency stop input to the drive. If a Fast
Stop command is input while the drive is running, the drive will decelerate to a stop by the
deceleration time set to C1-09 (refer to C1-09: Fast Stop Time on page 79). The drive can
only be restarted after is has come to a complete stop, the Fast Stop input is off, and the Run
command has been switched off.
• To trigger the Fast Stop function with a N.O. switch, set H1- = 15
• To trigger the Fast Stop function with a N.C. switch, set H1- = 16
Figure 1.49 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.
