WARNING
●To prevent an electric shock, turn off the power and wait for 15 minutes or more (20 minutes or more
for the converter unit and drive unit) before starting wiring and/or inspection.
●To prevent an electric shock, ground the servo amplifier.
●To prevent an electric shock, any person who is involved in wiring should be fully competent to do the
work.
●To prevent an electric shock, mount the servo amplifier before wiring.
●To prevent an electric shock, connect the protective earth (PE) terminal of the servo amplifier to the
protective earth (PE) terminal of the cabinet, then connect the grounding lead wire to the ground.
●To prevent an electric shock, do not touch the conductive parts.
WARNING
●To prevent an electric shock, do not operate the switches with wet hands.

ABOUT THE MANUAL
e-Manuals are Mitsubishi Electric FA electronic book manuals that can be browsed with a dedicated tool.
e-Manuals enable the following:
• Searching for desired information in multiple manuals at the same time (manual cross searching)
• Jumping from a link in a manual to another manual for reference
• Browsing for hardware specifications by scrolling over the components shown in product illustrations
• Bookmarking frequently referenced information
• Copying sample programs to engineering tools
If using the servo for the first time, prepare and use the following related manuals to ensure that the servo is used safely. For
the related manuals, refer to the User's Manual (Introduction).
When reading this manual to use a drive unit, substitute "drive unit" for "servo amplifier".

Precautions
• While the linear encoder and the linear servo motor should be oil and dust proofed, oil and dust proofing are especially
important for the linear encoder. For details, contact the manufacturer of the linear encoder being used.
• Use the linear encoder cables specified in this chapter. Using products other than those specified may cause a malfunction.
• Contact the manufacturer of the linear encoder being used for information on specifications, performance and guarantees.
• If the linear encoder is incorrectly installed, an alarm or position mismatch may occur. In such situations, refer to the
following check points and ensure that the linear encoder is installed in a suitable environment.
Check that the gap between the head and scale is correct.
Check that the scale head is not rolling or yawing (i.e., that the scale head is not loose).
Check the surface of the scale for dust and scratches.
Check that the vibration and temperature are within the specified range.
Check that the speed is within the permissible range without overshooting.
• Refer to the following page for combinations of linear encoders and servo amplifiers.

connectors
• When using 3M shell kits (36310-3200-008 or 36310-F200-008) or the Molex connector set (54599-1019), ensure the
external conductor of the shielded cable is firmly in contact with the ground plate before attaching the connector shell.

Fabricating the encoder cable
Fabricate the encoder cable using the MR-ECNM connector set as shown below. The encoder cable may be as long as 30 m.
■Encoder cable 1
*1 Encoder cables that meet the following specifications are recommended.
*2 The signals of pins 3 and 4 of the CN2L connector are as follows.
Pin 3: MR2
Pin 4: MRR2
*3 Do not connect anything to the pins that are marked with a diagonal line. Securely connect the external conductor of the shielded cable
to the ground plate and fix it to the connector shell.
