4-1 Motor cables and output rod movement directions
When (+) is connected to the white motor cable and (-) to the black cable, the output rod moves in the pushing
direction.

☆
The insulation resistance at the encoder section is checked sufficiently during the pre-shipment product inspection.
Please do not measure yourself.
4-3 Handling lead lines
Do not apply tension of 5 N (0.5 kgf) or more to the motor and encoder cables.
Install the lead line with slack and do not apply more tension than specified.
When the lead line curvature is required for use, set the curvature radius to 40mm or more.
4-4 Extension cable for motor
Use extension cables with the conductor cross-sectional area of 0.1 mm
2
or more for the motor. To avoid noise
induction to surrounding signal circuits, we recommend that you use shielded cables
4-5 Extension cable for encoder
◆
Twisted shielded cable is recommended for encoder extension cable. Shielded cable can also be used when
the transmission distance is shorter than about 2 m with little noise.
◆
Keep the encoder extension cable length under 10 m.
Check the following when using extension cables.
a) Check the supplied voltage at the encoder cable end if it goes out of the specified range due to the voltage
drop caused by resistance.
b) Check that a delay in signal pulse rise is not caused by the stray capacitance of the cable.
Please contact us when cable length exceeds 10 m.
◆
Do not use a single cable for wiring encoder signal lines and motor power lines.
Also, when the same cable is used for the signal lines for other equipment, take measures so that the encoder
is not affected by noise from those signal lines.
◆
Design the interface of the encoder signal properly so that the signal is not affected by noise.
