Setting 12, 13: Forward Jog, Reverse Jog
Digital inputs programmed as Forward Jog (H1-
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 more, 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 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-
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
Time on page 141). 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-
• To trigger the Fast Stop function with a N.C. switch, set H1-
Figure 5.51 shows an operation example of Fast Stop.
