Allen-Bradley PowerFlex 70 Reference Manual

2-68 Digital Inputs
The drive will not jog while drive is running or while “Stop - Clear
Faults” input is open. Start has precedence
.
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] and [Logic Mask] parameters, the terminal block becomes
direction owner as soon as one (or both) of the “Jog Forward” or “Jog
Reverse” input functions is closed.
• Speed select 1, 2, and 3
One, two, or three digital input functions can be used to select the speed
reference used by the drive, and they are called the Speed Select input
functions. The current open/closed state of all Speed Select input
functions combine to select which source is the current speed reference.
There are 8 possible combinations of open/closed states for the three
input functions, and thus 8 possible parameters can be selected. The 8
parameters are: [Speed Ref A Sel], [Speed Ref B Sel], and [Preset Speed
2] through [Preset Speed 7].
If the Speed Select input functions select [Speed Ref A Sel] or [Speed
Ref B Sel], then the value of that parameter further selects a reference
source. There are a large number of possible selections, including all 7
presets.
If the input functions directly select one of the preset speed parameters,
then the parameter contains a frequency that is to be used as the
reference.
!
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.
