Measure the
insulation
resistance.
At least once a
year
Disconnect the Servomotor
from the SERVOPACK and
measure the insulation resis-

lation resistance meter.
(Measurement method:
Measure the resistance
between phase U, V, or W
on the Servomotor’s power
line and FG.)
The insulation is normal if
the resistance is 10 M
or
higher.
If the resistance
is less than 10
M
, contact
your Yaskawa
representative.
Replace the
oil seal.
At least once every
5,000 hours
Contact your Yaskawa rep-
resentative.
