Figure 65: Home Setup View

Deceleration - Is the average deceleration rate used to decelerate from the target velocity to

zero velocity at the completion of the home.

Home Offset – By selecting a specified offset, the home will travel at a set velocity until the

home reference signal is detected, then travel an additional set distance, before coming to a

stop. The deceleration ramp begins at the proper time, to ensure the home completes precisely

at the specified offset distance after the home reference was detected. In order to decelerate

to a stop immediately upon detecting the home reference, select the “Calculated Offset” radio

box.

Limit Distance – Is the maximum incremental distance the home move will travel without

seeing a home reference signal. If the home move does travel this distance without seeing a

home reference, it will come to a stop exactly at this point, and the Home.0.LimitDistHit

source will activate. If the box is left unchecked, the home move will continue without limit,

until a home reference is seen.

Index Setup

Next, setup any indexes required by your application. Select one of the indexes from the

hierarchy window. Figure 11 shows Index0 (renamed Position A).
