The speed may be changed during rotation. In this case, the values set in parameters No. PC10, PC11
and 12 are used for acceleration/deceleration.
When the speed has been specified under any internal speed command, it does not vary due to the
ambient temperature.
(2) Speed reached (SA)
SA turns on when the servo motor speed has nearly reached the speed set to the internal speed command
or analog speed command.
