SlotX IO Direction
SlotX.IO.#.Direction
This parameter is only available when an SM-I/O Plus
Option module has been populated in one of the Unidrive
SP slots.
The X in “SlotX” defines the slot number that the SM-I/O
Plus module has been fitted in. For example, if the I/O Plus
module is in slot 2, the parameter would be named
Slot2.IO.#.Direction.
The first three digital I/O points on the SM-I/O Plus module
(pins 2, 3, and 4) are configured as Inputs or Outputs using
PowerTools Pro software. The SlotX.IO.#.Direction
parameter is used to configure whether the I/O point acts
as a digital input or digital output. Valid entries for this
parameter are selInput or selOutput. This parameter is
modified automatically when the user changes the settings
on the Slot X view.
SlotX IO Status
SlotX.IO.#.In
This parameter is only available when an SM-I/O Plus
module has been populated in one of the Unidrive SP slots.
The X in “SlotX” defines the slot number that the SM-I/O
Plus module has been fitted in. For example, if the I/O Plus
module is in slot 2, the parameter would be named
Slot2.IO.#.In.
The first three digital I/O points on the SM-I/O Plus module
(pins 2, 3, and 4) are configured as Inputs or Outputs using
PowerTools Pro software. The “.In” at the end of the
parameter name is optional, therefore this parameter is
often referred to as simply SlotX.IO.#. If the I/O point has
been configured as a digital input, then the SlotX.IO.#.In
signal can be used in a user program to check the status of
inputs, or on the Assignments view to activate different
signals.
N
ote
This parameter will appear on the Assignments view
under the Inputs group of Sources even if the I/O point
has been configured as a digital output.
SlotX IO Name
SlotX.IO.#.Name
This parameter is only available when an SM-I/O Plus
module has been populated in one of the Unidrive SP slots.
The X in “SlotX” defines the slot number that the SM-I/O
Plus module has been fitted in. For example, if the I/O Plus
module is in slot 2, the parameter would be named
Slot2.IO.#.Name.
Each digital I/O point on the SM-I/O Plus module can be
given a name. The name can be used in a user program to
reference a specific I/O point. The name can be up to 12
alphanumeric characters, but must begin with a
non-numeric character.
Slot X IO State
SlotX.IO.#.Out
This parameter is only available when an SM-I/O Plus
module has been populated in one of the Unidrive SP slots.
The X in “SlotX” defines the slot number that the SM-I/O
Plus module has been fitted in. For example, if the I/O Plus
module is in slot 2, the parameter would be named
Slot2.IO.#.Out.
The first three digital I/O points on the SM-I/O Plus module
(pins 2, 3, and 4) are configured as Inputs or Outputs using
PowerTools Pro software. The “.Out” at the end of the
parameter name is optional, therefore this parameter is
often referred to as simply SlotX.IO.#. If the I/O points have
been configured as digital outputs, then the SlotX.IO.#.Out
signal can be used in a user program to activate an output,
or on the Assignments view to activate when a specified
Source event activates. If assigned to a source on the
assignments view, when the source event activates, the
output that it is assigned to will turn on.
N
ote
This parameter will appear on the Assignments view
under the Outputs group of Destinations even if the I/O
point has been configured as a digital input.
SlotX Lines Per Revolution Divider
SlotX.LinesPerRevDivider
This parameter is available only when using a
SM-Universal Encoder Plus module. The Lines Per Rev
Divider text box provides direct access to parameter x.46
from the SM-Universal Encoder Plus module configuration
menu. This parameter is used in applications with a linear
motor where one electrical revolution does not correspond
to a whole number of encoder counts or sin waves. This
allows the user to enter a whole number of counts in the
Equivalent Lines Per Rev parameter when dividing by the
LPR Divider parameter yields the true lines per rev for the
application. See the SM-Universal Encoder Plus section of
this manual or the SM-Universal Encoder Plus User Guide
for more information.
SlotX Resolver Poles
SlotX.Poles
This parameter is available only when using a
SM-Resolver Module. The Resolver Poles text box
provides direct access to parameter x.15 from the
SM-Resolver module configuration menu. The setting of
this parameter allows the drive to properly read the position
and velocity feedback from the resolver hardware. The
number of poles of the resolver will define how many
electrical cycles will be seen from the resolver per single
