Typical Set Home Move Data Tables

Before executing a Set Home move, set Source B for the Equal
instruction in Figure 9.1 to 2. A Set Home command to set the
command position to –1.0 is initiated if the float data table is:

And the integer data table is:

Using the Set Retract Position Command

The Set Retract Position command sets the internal Retract Position
equal to the specified Retract Position . Set Retract Position
parameters for word 5, bit 2 appear in the table below.

1

s = Slot number for the SLC Servo Module.

The speed and time to reach speed are set accordingly and used
during the Retract Position move. This is the position that the axis
goes to when the discrete Retract Position bit gets set. This function is
useful when you want to set up a safe location for the axis to take
refuge in an emergency situation.

This operation can only be performed if the following occurs:

SLC Servo Module is out of Estop

There is no motion in progress

Axis is homed
