60
℃ (Note 3)
Service/storage humidity: 20 to 80%RH (no condensation)
Resistance to vibration while transporting or mounting the
motor: 25 m/s2 (frequency: 10 to 400Hz)
Resistance to impact while transporting or mounting the
motor: 300 m/s2
No dust, metal powder, corrosive gas, inflammable gas, or oil
mist.

Mounting direction
Output shaft facing up
Note 1: The table above shows the values for the output shaft.
Note 2: The values in the table are obtained when connected to the HA-770 Servo Driver
Note 3: The values for repeatability and absolute positional accuracy are measured with the mounting direction of
the output shaft facing up, and in an environment at a temperature of 23±0.3
℃
, with 50
％
humidity. Refer to
the "Notices for maintaining accuracy" on the next page when you use the motor.
Note 4: These values are after the angular position of the servo driver is corrected.
In order to enable angular position correction, it is always necessary to execute the originating operation by
the servo driver.
