Method 7 & 11: Homing using the home input and z-index. 

Method 7 and 11 will home the motor using the home input and z-index in the positive 
and negative directions, respectively. When the homing routine is started, the motor 
ramps to the Home Switch Speed until the home switch is triggered which, at that time, 
the motor decelerates to the Zero Position Speed.  At Zero Position Speed the motor 
continues to move until the Z index channel is triggered and at that time the motor 
changes direction and moves by the defined home offset. The final position is marked as 
the home position.

Method 17 & 18: Homing using the limit inputs only. 

Method 17 and 18 will home the motor using the limit inputs only in the positive and 
negative direction, respectively. When the homing routine is started

, 

the motor will 

accelerate to the Home Switch Speed.  As soon as the limit input is triggered, the motor 
ramps down to the Zero Position Speed and moves away from the limit input triggered 
position by the home offset, depending on the home limit error correction amount. The 
final position at the end of the move will be referenced as zero.

Method 19 & 20: Homing using the home input only. 

Method 19 and 20 will home the motor using the home input only in the positive and 
negative direction, respectively. When the homing routine is started

, 

the motor will ramp 

up to the Home Switch Speed.  As soon as the home input is triggered, the motor ramps 
down to the Zero Position Speed and changes direction.  When ramp down is done, the 
motor will move back by the Home Offset amount.
