 Operation
• Separate the I/O signal cables for control circuits from the power cables both inside and outside
the control panel to reduce the influence of noise from the power cables.
If the I/O signal lines and power lines are not separated properly, malfunction may occur.
• Follow the procedures and instructions in the user’s manuals for the relevant products to per-
form 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 subse-
quent 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 out-
put 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
MP3000 Series Motion Control User’s Manual (Manual No. SIEP C880725 11)
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.
