11.6.5.1 Starting reference search/setting the reference directly
By setting the HM_bActivateHoming control input to TRUE, the reference search in the selected
homing mode is started.
• During reference search, the HM_bActive status output is set to TRUE.
• By setting the status output HM_bHomePosAvailable to TRUE, it is already signalised during the
reference search that the home position has been found. Depending on the homing mode
selected, the drive traverses further on to the target position set in C02643 .
• When the reference search is completed, the HM_bActive status output is reset to FALSE and the
HM_bDone status output is set to TRUE.
11.6.5.2 Loading home position via input
By setting the control input HM_bLoadHomePos to TRUE, the "Tool position" that is pending at input
HM_dnHomePos_p is manually accepted as home position during the drive is at standstill. This is
also possible if the controller is inhibited.
• The HM_bDone status output is set to TRUE for one cycle.
• The HM_bHomePosAvailable status output is set to TRUE.

Note!
In the homing mode "100: Set reference directly" no reference search is started, but the
home position set in C02642 is directly accepted.

Note!
For the encoderless motor control types (from software version V3.0) the following
applies:
If V/f control or sensorless vector control has been selected, this function is only effective
if the position controller has also been selected for the position control
( C02570 = "2: position controller active").
For the encoderless motor control types (from software version V5.0) the following
applies:
If the V/f control or sensorless vector control is selected, this function can be activated
irrespective of the use of the position controller.
