1.1Precautions
— 1-3 —
Perform noise reduction and grounding properly.
If the signal line is noisy, vibration or malfunction
will result.
Install the system according to the following pre-
cautions.
D Separate high-voltage cables from low-voltage cables.
D Use cables as short as possible.
D Be sure to ground (ground resistance 100 Ω or
less) for the Servomotor and Servopack.
D Never use a noise filter for the power supply
between the Servomotor and Servopack.
Do not perform continuous operation under overhanging load.
Continuous operation cannot be performed by ro-
tating the motor from the load and applying regen-
erative braking. Regenerative braking by the Ser-
vopack can be applied only for a short period,
such as when the motor is stopped.
Do not operate the Servomotor by turning the power ON and OFF.
Frequently turning the power ON and OFF causes
the internal circuit elements to deteriorate. Always
start or stop the Servomotor by using reference
pulses.
