 Operation
 Follow the procedures and instructions in the user's manuals for the relevant Machine Control-
lers to perform normal operation and trial operation.
Operating mistakes while the Servomotor and machine are connected may damage the machine or
even cause accidents resulting in injury or death.
 Implement interlock signals and other safety circuits external to the Machine Controller to
ensure safety in the overall system even if the following conditions occur.
• Machine Controller failure or errors caused by external factors
• Shutdown of operation due to Machine Controller detection of an error in self-diagnosis and the sub-
sequent turning OFF or holding of output signals
• Holding of the ON or OFF status of outputs from the Machine Controller due to fusing or burning of
output relays or damage to output transistors
• Voltage drops from overloads or short-circuits in the 24-V output from the Machine Controller and the
subsequent inability to output signals
• Unexpected outputs due to errors in the power supply, I/O, or memory that cannot be detected by
the Machine Controller through self-diagnosis.
There is a risk of injury, device damage, or burning.
 Observe the setting methods that are given in the manual for the following parameters.
• Parameters for absolute position detection when the axis type is set to a finite-length axis
• Parameters for simple absolute infinite-length position control when the axis type is set to an infinite-
length axis
If any other methods are used, offset in the current position when the power supply is turned OFF
and ON again may result in device damage.
 OL48 (Zero Point Position Offset in Machine Coordinate System) is always valid when the
axis type is set to a finite-length axis. Do not change the setting of OL48 while the
Machine Controller is operating.
There is a risk of machine damage or an accident.
