Setting 12, 13: Forward Jog, Reverse Jog
Contact inputs programmed as Forward Jog (H1-
= 12) and Reverse Jog (H1-
= 13) will be Jog inputs that do
not require a Run command. Closing the terminal set for Forward Jog input will cause the drive to ramp to the Jog
frequency reference (d1-17) in the forward direction. The Reverse Jog will cause the same action in the reverse direction.
The Forward Jog and Reverse Jog command can be set independently.
Note:
The Forward Jog and Reverse Jog commands override all other frequency references. However, if the drive is set to prohibit
reverse rotation (b1-04 = 1), then activating Reverse Jog will have no effect. If both the Forward Jog and Reverse Jog are input
simultaneously for 500 ms or longer, an alarm will occur and the drive will ramp to stop.

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 a stop (specific stopping methods can be selected for some faults such as L8-03 for Overheat
Pre-Alarm Operation Selection). Once the Run command is turned OFF, the fault can be cleared for restarting the drive
either by pressing RESET on the digital operator or by closing a contact 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 turn off 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 within the deceleration time set in C1-09 (
). The drive can only be restarted after it 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 an N.O. switch, set H1-
= 15.
• To trigger the Fast Stop function with an N.C. switch, set H1-
= 17.

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.
