To support many different applications, the SM-Universal
Encoder Plus module can provide several different supply
voltages. Select from 5V, 8V, or 15V to be provided from
the module hardware. See the SM-Universal Encoder Plus
section of this manual or the SM-Universal Encoder Plus
User Guide for more information.
SlotX Resolver Equivalent Lines Per Rev
SlotX.EncoderLinesPerRev
This parameter has slightly different functionality when
using a SM-Resolver module. The Equivalent Lines Per
Rev list box provides direct access to parameter x.10 from
the SM-Resolver module configuration menu. The setting
of this parameter determines the maximum motor speed
and the simulated encoder output resolution. Refer to the
chart in the SM-Resolver section of this manual for proper
setting of this parameter. Improper setting could result in
the motor max speed being clamped to a value lower then
the motor actual capability. For even more information see
the SM-Resolver User Guide.
SlotX Encoder Turns
SlotX.EncoderTurns
This parameter is available when using a SM-Universal
Encoder Plus module. The Encoder Turns text box
provides direct access to parameter x.09 from the
SM-Universal Encoder Plus module configuration menu.
This parameter defines how many revolutions will be
recorded before the Revolution Counter (x.04) rolls over.
The parameter is entered in a number of bits of resolution.
To determine the associated number of revs, use the
formula: Revs before rollover = 2
n
where n is the value of
Encoder Turns. See the SM-Universal Encoder Plus
section of this manual or the SM-Universal Enc Plus User
Guide for more information.
SlotX Encoder Type
SlotX.EncoderType
This parameter is available only when using a
SM-Universal Encoder Plus module. The Encoder Type list
box provides direct access to parameter x.15 from the
SM-Universal Encoder Plus module configuration menu.
This parameter allows one SM-Universal Encoder Plus
module to support many different encoder types. Select the
desired type of encoder from this list box. See the
SM-Universal Encoder Plus section of this manual or the
SM-Universal Encoder Plus User guide for more
information.
SlotX Wire Break Detect Checkbox.
SlotX.Error DetectionLevel
This parameter is available only when using a
SM-Resolver module. The Wire Break Detect checkbox
provides direct access to parameter x.17 from the
SM-Resolver module configuration menu. If the checkbox
is not active (unchecked), the wire break trip will never be
active. For more information, see the SM-Resolver User
Guide.
SlotX Resolver Excitation
SlotX.Excitation
This parameter is available only when using a
SM-Resolver module. The Excitation list box provides
direct access to parameter x.13 from the SM-Resolver
module configuration menu. This parameter defines the
voltage level of the excitation signal sent to the resolver
hardware. Depending on the turns ratio of the resolver (2:1
or 3:1), the Unidrive SP provides a 4V or 6V signal to the
resolver. For more information see the SM-Resolver User
Guide.
SlotX Input Status
SlotX.Input.#.In
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.Input.#.In.
The last three digital I/O points on the SM-I/O Plus module
are defined as digital inputs only (pins 6, 7, and 8). The “.In”
at the end of the parameter is optional, so this signal is
most often referred to simply as SlotX.Input.#. These
inputs can be used in a user program, or on the
Assignments view to activate different destination events.
These inputs are updated at the Trajectory Update Rate
found on the Setup view in PowerTools Pro.
SlotX Input Name
SlotX.Input.#.Name
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.Input.#.Name.
Each digital input 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 input. The name can be up to 12
alphanumeric characters, but must begin with a
non-numeric character.
