3.4.2 Internal speed control mode
(1) Speed setting
(a) Speed command and speed
The servo motor is run at the speeds set in the parameters.
Forward rotation (CCW)
Reverse rotation (CW)
The following table indicates the rotation direction according to forward rotation start (ST1) and reverse
rotation start (ST2) combination.
(Note 1) External input signals (Note 2) Rotation direction
ST2 ST1
Internal speed commands
0 0 Stop (Servo lock)
0 1 CCW
1 0 CW
1 1 Stop (Servo lock)
Note 1. 0: ST1/ST2-VIN off (open)
1: ST1/ST2-VIN on (short)
2. Releasing the torque limit during servo lock may cause the servo motor to suddenly rotate according to the position
deviation from the instructed position.
The forward rotation start (ST1) and reverse rotation start (ST2) can be assigned to any pins of the
connector CN1 using parameters No.43 to 48.
Generally, make connection as shown below.
