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
Up/Down 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-
Note: Remove the Up/Down command prior to resetting a fault. Fault Reset commands are ignored while the Up/Down command is
present.
Setting 15, 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
Stop Ramp on page 110). The drive can only be restarted after bringing the drive to a complete stop, turning off the Fast
Stop input, and switching off the Up/Down command.
• To trigger the Fast Stop function with a N.O. switch, set H1-
• To trigger the Fast Stop function with a N.C. switch, set H1-
Figure 5.11 shows an operation example of Emergency 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-

Setting 20 to 2F: External fault
The External fault command stops the drive when problems occur with external devices.
To use the External fault command, set one of the multi-function digital inputs to any value between 20 to 2F. The digital
operator will display EF
For example, if an external fault signal is input to terminal "EF3" will be displayed.,
