2：Trial run control mode;
3：JOG control mode;
4：Encoder zeroing mode;
5：Open loop mode(for motor and encoder test)
① Position control mode Position instruction is input from
the pulse input interface.
② Speed control mode Speed instruction is input from the
input terminal. The internal speed is selected by the
combination of SC1 and SC2.
SC1 OFF，SC2 OFF ：internal speed 1
SC1 ON，SC2 OFF ：internal speed 2
SC1 OFF，SC2 ON ：internal speed 3
SC1 ON，SC2 ON ：internal speed 4
③ Trial run control mode Speed instruction is input from the
keyboard, which is used for drive unit and servo motor test.
④ JOG control mode In this mode, pressing down ↑ key and
holding it on, the motor runs by JOG speed, releasing the
key, the motor stops and keeps zero speed; pressing down
↓ key and holding it on, the motor runs reversely by JOG
speed; releasing the key, the motor stops and keeps zero
speed.
⑤ Encoder zeroing mode It is used for encoder factory
zeroing adjustment of motor.
