The speed may be changed during rotation. In this case, the values set in parameters No. 11 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-SG are connected when the servo motor speed nearly reaches the speed set to the internal speed
command or analog speed command.
(3) Torque limit
As in Section 3.4.1 (5).
