Installation procedure
1.3.1 Assembling the servo motor
▷
Warning : While assembling the servo motor, avoid dropping it.
▷
Caution : While mounting the servo motor horizontally, the connector should be facing
downward.
▷
The servo motor can be mounted horizontally or vertically.
▷
To prevent vibrations, the motor shaft and the loading shaft should be precisely aligned which
will allow for the coupling and bearing life to last longer. Use flexible coupling when connecting
directly to the load.
① The outer part of the coupling should be measured at four equidistant points, each 90
˚
degrees apart so that the gap between the maximum and the least readings should not
exceed 0.03mm.
② The center point of the motor and the loading shaft should be precisely aligned.
▷
Avoid excessive radial and thrust load to the motor shaft and also avoid impact that is more
than 10G when mounting the gear, coupling, pulley and etc. at the same time.
▷
A minus load means that while the motor is rotating according to the load, it is successively
operating while it is on regenerative brake. The capacity of the regenerative brake is short term
rating specification, thus it should not be used in minus load.
