Setting 12/13: FJOG/RJOG Reference
Digital inputs programmed as Forward Jog (H1-oo =
12) and Reverse Jog (H1-oo = 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 more, an external fault will occur and the drive will stop using the method set by b1-03.

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-oo = 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 143). 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-oo = 15
•
To trigger the Fast-stop function with a N.C. switch, set H1-oo = 17
Figure 5.50 shows an operation example of Fast-stop.
