Home Initiate
Home.#.Initiate
When activated, this destination will initiate the specified
home. Home will not initiate if an index, jog, program, or
stop is currently active.
Home Limit Distance
Home.#.LimitDist
This parameter places an upper limit on the incremental
distance traveled during a home. If no home reference is
found the motor will decelerate to a stop at the limit
distance and activate the Home.#.LimitDistHit event.
Enable Limit Distance
Home.#.LimitDistEnable
This parameter enables the specified Home.#.LimitDist. If
not enabled, the home will run indefinitely until the home
reference is found.
Home Limit Distance Hit
Home.#.LimitDistHit
This source is activated when the home sensor is not found
before the Home Limit Distance is traveled.
Home Name
Home.#.Name
User name for the specified home.
Home Offset Type
Home.#.OffsetType
Selects calculated or specified home offset. Calculated
offset is the distance traveled during the deceleration ramp
from the home velocity. The specified offset allows the user
to choose an exact offset from the Home Reference.
If On Sensor
Home.#.OnSensorAction
If the home sensor input is active when the home is
initiated, this parameter determines the direction of motion.
Two selections are possible. If "Back off before homing" is
selected, the motor will turn in the opposite direction of the
home until the home sensor is clear and then begin the
home. If "Go forward to next sensor" is selected, the motor
will turn in the commanded direction until the next rising
edge of the sensor is seen. If using Modbus to view or
modify this parameter, 1= Back off before homing, 0 = Go
forward to next sensor.
Home Reference
Home.#.Reference
This parameter determines how the reference position is
determined. The parameter can have one of three different
values: 'Sensor', 'Marker', 'Sensor then Marker'. When the
home reference is 'Sensor' the rising edge of the 'Home
Sensor' input function is used to establish the reference
position. When the home reference is 'Marker' the rising
edge of the motor encoder's marker channel is used to
establish the reference position. When the home reference
is 'Sensor then Marker' the reference position is
established using the first marker rising edge after the
Home Sensor input function goes active.
Home Sensor Trigger
Home.#.SensorTrigger
This destination is usually a sensor input used as a
reference for the home. This event is only used if the home
is defined by sensor or by sensor and marker.
Home Specified Offset
Home.#.SpecifiedOffset
The specified offset parameter allows the user to specify
an exact offset relative to the Home Reference. The
commanded motion will stop at exactly the offset distance
away from the sensor or the marker as specified.
Home Time Base
Home.#.TimeBase
The time base selects either realtime, which allows
velocities, acceleration and deceleration to be based on
real time, or synchronized, which allows for an external
synchronization signal.
Home Velocity
Home.#.Vel
This parameter sets the target velocity for all of moves in
the home. The sign determines the home direction.
Positive numbers cause motion in the positive direction
and negative numbers cause motion in the negative
direction in search of the home sensor.
Index Any Command Complete
Index.AnyCommandComplete
This source is active when any index motion command is
completed. If a stop is activated before the index has
completed, this destination will not activate. Deactivated
when any index command is initiated.
