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 126). 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- = 17
Figure 5.48 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 16: Motor 2 Selection
The drive has the capability to control two motors independently. A second motor may be selected using a multi-function
digital input (H1- = 16) as shown in Figure 5.49.
