7-30 Setting Up Your SLC Servo Module
Axis Parameters
Use the axis parameters in the following table to specify your axis
configuration.
Homing Parameters
Use the homing parameters in the following table to home each axis.
Name Location Description
Rollover Position M0:s.12,13 Value of the position register when it changes
from the highest value to 0 if moving in the
positive direction. Value of the position register
when it changes from 0 to the highest value if
moving in the negative direction in position
units.
Software Overtravels
Used M0:s.0/7 Determines whether software overtravel limits
are used.
Positive Overtravel
Limit M0:s.8,s.9 Position value of the positive software
overtravel limit in position units.
Negative Overtravel
Limit M0:s.10,s.11 Position value of the negative software
overtravel limit in position units.
Reversal Error Value M0:s.22,s.23 Distance the control adds to the commanded
motion when the axis changes direction in
position units.
Name Location Description
Home Type M0:s.0/9,
M0:s.0/10 Specifies the type of homing to be used by the
SLC Servo Module.
Home Position M0:s.14,s.15 The position value the control puts into the
current position after a homing operation.
Home Calibration M0:s.16,s.17 The distance to the home position from the first
encoder marker detected after the limit switch
deactivates while the axis is moving off the
limit switch.
Final Move to Which
Marker? M0:s.0,11 This bit specifies which marker the axis needs
to move to for the final move of both the
Homing to a Marker and Homing to a Limit
Switch and Marker home types.
Final Move to
Marker? M0:s.0,12 This bit specifies if the final move to the marker
is performed for the axis.
Limit Source M0:s.1,0 Specifies the source for the home limit to be
either the backplane or the termination panel.
