Do not change the set values with asterisk (*) mark as they are functions for maintenance. If the standard set value set at the
time of delivery is changed, it is in danger of causing the machine to be broken or the performance to be deteriorated.
If it is necessary to change the set value, please purchase the Engineer’s Manual and follow the instructions.
(Descriptions of setting in this list are the standard values at the time of delivery of DDL-9000A.)
However, contents of function setting are subject to change for improvement of function and performance without notice.
Items with mark are displayed when the machine heads of LH-4168, LH-4168D and LH-4188 are selected.
