Parameter Descriptions

Limit Distance Hit Home.#.LimitDistHit

This source is activated when the home sensor is not found before the Home Limit Distance

is traveled.

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.

End of Home Position Home.#.EndPosn

This parameter defines the drive position at the completion of a home. Typically used to

define the machine coordinate home position.

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.

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.

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.
