Settings 12 and 13: Forward Jog, Reverse Jog

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), activating Reverse Jog will have no effect. Inputting both the Forward Jog and Reverse Jog are simultaneously for 500 ms or

longer will trigger an alarm will and the drive will ramp to stop.

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 Run

command, clear the fault either by pressing the RESET key on the HOA keypad or closing a digital input configured as a Fault

Reset (H1-oo = 14).

Note:

Remove the Run command prior to resetting a fault. Fault Reset commands are ignored while the Run command is present.

Settings 15 and 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 (

Refer to C1-09: Fast Stop Time on page

52

). The drive can only be restarted after bringing the drive to a complete stop, turning off the Fast Stop input, and switching

off the Run command.
• To trigger the Fast Stop function with an N.O. switch, set H1-oo = 15.
• To trigger the Fast Stop function with an N.C. switch, set H1-oo = 17.

Figure 1.35

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-oo = 12).
