Digital Inputs
76
The drive will not jog while running or while the "Stop - Clear Faults" input is
open. Start has precedence.
ATTENTION: If a normal drive start command is received while the
!
drive is jogging, the drive will switch from jog mode to run mode. The
drive will not stop, but may change speed and/or change direction.
The terminal block bit must be set in the [ Jog Mask] and [Logic Mask]
parameters in order for the terminal block to cause the drive to jog using this
input function.
• Jog Forward, Jog Reverse
An open to closed transition on one input or both inputs while drive is
stopped will cause the drive to jog unless the "Stop - Clear Faults" input
function is configured and open. The table below describes the actions taken
by the drive in response to various states of these input functions.

If one of these input functions is configured and the other one isn't, the above
description still applies, but the unconfigured input function should be
considered permanently open.
The drive will not jog while drive is running or while "Stop - Clear Faults"
input is open. Start has precedence
ATTENTION: If a normal drive start command is received while the
!
drive is jogging, the drive will switch from jog mode to run mode. The
drive will not stop, but may change speed and/or change direction.
The terminal block bit must be set in the [ Jog Mask], [Direction Mask], and
[Logic Mask] parameters in order for the terminal block to cause the drive to
jog using these input functions.
Important: Direction control is an "Exclusive Ownership" function (see
Owners). This means that only one control device (terminal
block, DPI device, HIM, etc.) at a time is allowed to control
direction at a time. The terminal block must become direction
"owner" before it can be used to control direction. If another
device is currently the direction owner (as indicated by
[Direction Owner]), it will not be possible to jog the drive or
change direction by using the terminal block digital inputs
programmed for both Run and Direction control (i.e. Run/
Fwd).
If another device is not currently the direction owner (as indicated by
[Direction Owner]) and the terminal block bit is set in the [Direction Mask]
