Installation
The KDU Series motor drives mechanical load system at high accuracy.
When installing the motor, pay attention to precision and do not tap the output section of KDU Series
motor with a hammer, etc. Excessive impact may damage the encoder and make it impossible to
guarantee the positional accuracy.
Installation procedure
1. Adequately center the KDU Series mounting spigot and
the load position.
Note 1: Perform this alignment carefully, especially when a
rigid coupling is used. Even slight misalignment
may make it impossible to guarantee the positional
accuracy of the KDU Series motor
.
Note 2: Avoid all impact during mounting.
2. Fasten the KDU Series motor on the device with high-tension bolts.
Tighten them with a torque wrench to control the tightening torque.
Tightening torques are shown in the table below.

3. Mount the encoder interpolator.
This unit has a function for converting encoder signals into high-resolution digital signals. Fasten
securely. It is also necessary to always ground the interpolator and driver. If the grounding is
incomplete, positioning may not be performed correctly due to noise.
4. For details on wiring, refer to the HA-770 driver manual, Chapter 6 "Driver Installation".
5. Motor cable and encoder cable
Do not pull the cables with a strong force. The connection points may be damaged. Install the
cable with slack and do not to apply any tension to the motor. Provide a sufficient bending
radius (R = 40 mm or more), especially when the cable flexes.
Do not disassemble/reassemble the motor.
The motor uses many precision parts. Drops in accuracy and
performance due to disassembly and assembly by the customer are
not covered by the warranty.
