(b) Speed selection 1 (SP1) and speed limit values
At the initial condition, the speed limit values for the internal speed limits 0 and 1 can be selected using
the speed selection 1 (SP1).

When the speed is limited by the internal speed limits 0 to 7, the speed does not vary with the ambient
temperature.
(c) Limiting speed (VLC)
VLC turns on when the servo motor speed reaches the speed limited by the internal speed limits 0 to 7.
