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 Activate
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 Plus Activate
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.
Software Travel Limit Plus Position
SoftwareTravelLimitPlusPosn
The SoftwareTravelLimitPlusActive source is active when the SoftwareTravelLimitPlusPosn 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 enabled and
Absolute Position Valid is active.
Start Up
StartUp
This source can be used to trigger an event to occur on startup (when the Epsilon EP-P drive powers up or is rebooted). This source is typically
used to initiate a program or to initiate a home so that a machine will automatically home on power up or reboot. StartUp will activate when the
Epsilon EP-P drive has powered up and no faults are active. Startup may take as long as five seconds to activate. Depending on what the
Startup source is assigned to, the drive may need to be enabled to perform the function. If the drive is not enabled, the startup source cannot
initiate programs or motion. The source will remain active until the Epsilon EP-P drive is powered down.
Stop
Stop
Activate this destination to stop all motion and programs. If Stop is activated when a Jog, Index, Home or Program is in progress, they will
decelerate to zero speed at the Stop Decel ramp. When Stop is active, all Jog, Home, Index and Program initiate destinations will be ignored.
When it is deactivated, all level sensitive and active input functions (Jog.0.PlusActivate, Jog.0.MinusActivate, etc.) will become operational. For
example, if the Jog.PlusActivate input function is active when the Stop input function is deactivated, the Jog.Plus motion will initiate using the
acceleration found in the Jog.0.Accel parameter. This is level sensitive.
Stop Deceleration
StopDecel
Deceleration rate used when the Stop destination is activated.
Torque Command
TorqueCommand
This parameter is the torque command value before it is limited. The torque command may be limited by the motor’s rating, the amplifier’s
rating, the Torque Limit (if the Torque Limit Enable destination is active) or Current Foldback. Units for this parameter are defined in the Torque
Group on the User Units view.
Limited Torque Command
TorqueCommandLimited
This is the actual torque commanded to the motor. This value is the result after the TorqueCommand is limited by the current foldback or the
TorqueLimit value (if enabled).
Torque Level
TorqueLevel
This parameter is compared to the TorqueCommand. If the absolute value of the TorqueCommand is greater than or equal to the TorqueLevel
the TorqueLevelActive source is activated. This parameter is specified in Torque User Units.
