HC/HA motor
4. CASE AND STUDY OF A-MOTION REPLACEMENT
The following shows the replacement case study of the system which used standard A-Motion. Although
it will need some major maintenance, it is recommended to carry out the system batch update of 1) to use a
system for a long time with no system modification after the maintenance.
If the batch update including the change of servo amplifiers, servo motors, and servo networks is difficult
to carry out due to the period and cost of the maintenance, carry out 2) or 3). If any update will not be done,
refer to 4) Individual replacement support.
* Production will be
stopped in August, 2015.
