4.3.4 Home Configuration
In this page, you can set every detailed parameter related to the home
function. With well-defined parameters, moving objects can reach their
home precisely when requested.
Home mode : PCI-1241/42 provides different home modes to fulfill dif-
ferent needs. There are overall fourteen home modes, from mode0 to
mode13. Please refer to appendix C for further details.
Sensor mode : Here the electrical types of home sensors are defined. It
can be normal open or normal close.
Direction : Use this setting to set the initial direction to move towards
when the home command is issued. 0 means positive direction and 1
means negative direction.
Index Count : Used in home mode 2, 3, 4, 7, 8, 10, 11, and 12. If the
index count has been set as n, the motor will slow down or stop at the n+1
index input.
Home Offset : Represents the offset distance when the normal home point
was reached. It can be a positive or negative value.
Acc./Dec. Time : The acceleration/deceleration time interval when the
start/stop point was reached.
High Speed & Low Speed : You can accurately define the high speed and
low speed for home functions. Generally the motor will start with high
speed. When the home sensor is reached, the motor will switch to low
speed and position itself as close as possible to the home point.
