Current Limit Active
CurrentLimitActive
The Current Limit Active event activates when the Current Demand meets or exceeds the Current Limit parameter value. This event
can be found on the Assignments view and can be assigned to a digital output or other event to signal to the user when the current
is being limited by EZMotion. The event will deactivate when the Current Demand is less than the Current Limit value.
Current Limit Enable
CurrentLimitEnable
The user can limit the amount of current that the drive can generate by configuring the Current Limit in EZMotion. The Current Limit
Enable signal must be active for the current to be limited to the Current Limit value. The Current Limit Enable signal is not active by
default.
Decelerating
Decelerating
This source is active when EZMotion is decelerating. A normal index consists of 3 segments: Accelerating, At Velocity, and
Decelerating. Decelerating follows the accelerating segment and the At Velocity segment. When indexes are compounded to create
a complex motion profile, only the last index may contain a decelerating segment.
Define Home
DefineHome
This destination is used to set the Commanded Position to the value specified in the DefineHomePosn variable. On the rising edge
of this input function the absolute position is set equal to the DefineHomePosn and the AbsolutePosnValid output function (source) is
activated.
Define Home Position
DefineHomePosn
The DefineHome parameter is used to set the motors absolute position to the value stored in the DefineHomePosn variable. On the
rising edge of the DefineHome function the Commanded Position is set equal to the DefineHomePosn and the AbsolutePosnValid
source is activated.
Acceleration
DistanceRecovery.Accel
This parameter in user units is the acceleration rate for the distance recovery index.
DistanceRecovery.Decel
Deceleration
DistanceRecovery.Decel
This parameter in user units is the deceleration rate for the distance recovery index.
Enable Distance Recovery
DistanceRecovery.DistanceRecoveryEnable
Select the checkbox to enable the additive distance recovery index feature.
Velocity
DistanceRecovery.Vel
This parameter, in user units, is the velocity limit of the distance recovery index.
Characteristic Distance
DistUnits.CharacteristicDistance
This parameter is the distance the load travels (in user units) when the motor travels the characteristic length (in motor revolutions).
This parameter is used along with the DistUnits.CharacteristicLength to establish the relationship between user distance and actual
motor travel distance. See
User Units View on page 76.
Characteristic Length
DistUnits.CharacteristicLength
This parameter is the distance the motor travels (in whole number of revolutions) to achieve one characteristic distance of load
travel. This parameter is used along with the DistUnits.CharacteristicDist to establish the relationship between user distance and
motor travel distance. See
User Units View on page 76.
