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.

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.
