units, at the time when CaptureTriggered activated.
Captured Master Position Homed
Captured.#.CapturedMasterPosHomed
On the rising edge of the Capture Activate event, the
master axis position is captured (in counts). The captured
counts value is then converted into Master Distance User
Units and stored in the Captured Master Position
parameter. If the user redefines the zero position of the
master axis, the master position in User Units is zeroed
out, however the counts parameter is not. Therefore, if
another capture occurs after the position has been zeroed,
the value stored in the Captured Master Position
parameter will be off by the value of the master axis before
the position was zeroed out. This parameter is to be used
if the master axis position is redefined after power-up.
Clear Following Error
ClearFollowingError
Clear Following Error is a destination found in the Position
group on the Assignments view. When this destination is
activated, any following error that has accumulated will be
erased. Following Error is cleared by setting the
commanded position to the feedback position,
automatically resulting in a zero following error. The
SM-EZMotion module will deactivate the Clear Following
Error destination as soon as Following Error is zero.
Commanding Motion
CommandingMotion
This source activates when VelCommand is non-zero.
Current Demand
CurrentDemand
The current demand is read from the Unidrive SP
parameter 4.04. The units for the Current Demand are %
of rated current. 100% rated current is defined as the rated
current of the system (Motor Rated Current <
System
Rated Current <
Drive Rated Current).
This read-only parameter can be found on the Online tabs
of the Status and Current views.
Current Level
CurrentLevel
The SM-EZMotion module constantly monitors the amount
of current being output from the Unidrive SP. The user can
set the Current Level parameter such that when the
Current Demand from the drive is equal to or greater than
the Current Level, the Current Level Active event will
activate. This is simply a flag that can be used to indicate
to the user that a certain amount of current/torque is being
generated by the Unidrive SP.
Units for the Current Level are % Continuous. This means
that 100% is equal to the system rated current (Motor
Rated Current <
System Rated Current < Drive Rated
Current). This parameter is found on the Current view.
Current Level Active
CurrentLevelActive
The Current Level Active event activates when the Current
Demand meets or exceeds the Current Level 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 level is exceeded. The
event will deactivate when the Current Demand is less than
the Current Level value.
Current Limit
CurrentLimit
The user can limit the amount of current that the Unidrive
SP can generate by configuring the Current Limit in the
SM-EZMotion module. The Current Limit Enable signal
must be active for the current to be limited to the Current
Limit value. By default. the Current Limit Enable signal is
not active.
Units for the Current Limit are % Continuous. This means
that 100% is equal to the system rated current (Motor
Rated Current <
System Rated Current < Drive Rated
Current). This parameter is found on the Current view.
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 the
SM-EZMotion module. 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 Unidrive
SP can generate by configuring the Current Limit in the
SM-EZMotion module. 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 the SM-EZMotion module is
decelerating. A normal index consists of 3 segments:
