1: Speed control mode
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.
