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 mechanical revolution. The (# of Poles / 2) will equal the number of electrical cycles
per revolution. For more information see the SM-Resolver User Guide.
SlotX Relay Name
SlotX.Relay.#.Name
This parameter is only available when an SM-I/O Plus or SM-I/O 120V module has been populated in one of the Unidrive SP/Digitax
ST slots.
The X in “SlotX” defines the slot number that the I/O module has been fitted in. For example, if the I/O module is in slot 2, the
parameter would be named Slot2.Relay.#.Name.
Each relay output on the I/O module can be given a name. The name can be used in a user program to reference a specific relay
output if desired. The name can be up to 12 alphanumeric characters, but must begin with a non-numeric character.
SlotX Relay State
SlotX.Relay.#.Out
This parameter is only available when an SM-I/O Plus or SM-I/O 120V module has been populated in one of the Unidrive SP slots.
The X in “SlotX” defines the slot number that the I/O module has been fitted in. For example, if the I/O module is in slot 2, the
parameter would be named Slot2.Relay.#.Out.
The SM-I/O Plus (pins 21 and 23) and SM-I/O 120V (pins 10 and 12) modules have two relay outputs that can be used to control
devices that require more current than a standard digital output. The “.Out” at the end of the parameter name is optional, so this
parameter is often referred to simply as SlotX.Relay.#. This parameter can be used in a user program to activate the output (i.e.
Slot2.Relay.8 = On), or can be assigned to a Source on the Assignment view.
Enable Software Travel Limits
SoftwareTravelLimitEnable
Software travel limits can be used to limit machine travel. They are often setup inside the hardware travel limits to add a level of
protection from exceeding the machines travel limits. The SoftwareTravelLimitMinusActive source (output function) is active when
the SoftwareTravelLimitMinusPosn is reached or exceeded. Motion is halted using the TravelLimitDecel whenever a hardware or
software travel limit is hit or exceeded. Software travel limits are not active unless Absolute Position Valid is active.
Software Travel Limit Minus Active
SoftwareTravelLimitMinusActive
The SoftwareTravelLimitMinusActive source is active when the SoftwareTravelLimitMinusPosn is reached or exceeded. Motion will
come to a stop using the TravelLimitDecel ramp. Software travel limits are not active unless enabled and Absolute Position Valid is
active.
Software Travel Limit Minus Position
SoftwareTravelLimitMinusPosn
The SoftwareTravelLimitMinusActive source will activate when the SoftwareTravelLimitMinusPosn is reached or exceeded. Motion
will come to a stop using the TravelLimitDecel. Software travel limits are not active unless enabled and Absolute Position Valid is
active.
Software Travel Limit Plus Active
SoftwareTravelLimitPlusActive
The SoftwareTravelLimitPlusActive source is active when the SoftwareTravelLimitPlusPosn is reached or exceeded. Motion will
come to a stop using the TravelLimitDecel ramp. Software travel limits are not active unless enabled and Absolute Position Valid is
active.
