15.9.2 Replacing the Motor of the Motor Straight Type (Coupling Type)

: SA7C

[Items Required for Replacement]



Replacement

motor



Allen wrench



Scale



Grease

Other than cleanroom specification

Idemitsu Kosan

Daphne Eponex Grease No. 2

Cleanroom specifications

KURODA Precision Industries

C Grease



PC or teaching pendant

Caution: When replacing the motor, handle the replacement motor with due care. The actuator has been

shipped with the encoder adjusted to an optimal position, so do not crush the encoder unit. It
may displace the encoder, thus impairing proper actuator operation.

[Procedure]

1) Remove the motor-end cap affixing bolts using an Allen wrench.
