System Design and Installation
The following table shows the Servomotor leakage current for each Servo Driver model.
Driver
R7D-APA3L to -AP04L
R7D-APA3H to -AP04H
R7D-AP08H
Note 1. The above leakage current is for cases where Servomotor power line length is less than 5
meters. (It varies depending on the Servomotor cable length and the insulation.)
Note 2. The above leakage current is for normal temperature and humidity. (It varies depending on
the temperature and humidity.)

Improving Encoder Cable Noise Resistance
■
In order to improve the encoder's noise resistance, take the following measures for wiring and instal-
lation.
• Always use the specified Encoder Cables.
• If lines are interrupted in the middle, be sure to connect them with connectors, making sure that the
cable insulation is not peeled off for more than 50 mm. In addition, always use shielded cable.
• Do not coil cables. If cables are long and are coiled, mutual induction and inductance will increase
and will cause malfunctions. Always use cables fully extended.
• When installing noise filters for Encoder Cables, use clamp filters. The following table shows the
recommended clamp filter models.

• Do not place the Encoder Cable in the same duct as Control Cables for brakes, solenoids, clutches,
and valves.
Improving Control I/O Signal Noise Resistance
■
Positioning can be affected and I/O signals can error if control I/O is influenced by noise. Follow the
methods outlined below for the power supply and wiring.
• Use completely separate power supplies for the control power supply (especially 24 V DC) and the
external operation power supply. In particular, be careful not to connect the two power supply
ground wires. Install a noise filter on the primary side of the control power supply.
