There are two ways to use the override.
•
Apply the override to all operations from start to finish by turning ON the over-
ride enable/disable (bit 07 of command word m+1) and executing START.
•
Apply the override to operations following execution of the CHANGE OVER-
RIDE command. Set the override in advance and then make the change by
turning ON the CHANGE OVERRIDE bit (bit 12 of command word m+2). This
second method, changing the override during positioning, is the way that is il-
lustrated in this example.
