□ Operation of motion control and SS2 function
1. When the Servo ON command is enabled, the Servo Drive turns ON the Servo.
2. When an operation command is enabled, the command velocity to the Servomotor is set to 600
r/min.
3. When the SS2 function is executed, the Servo Drive shifts to the SOS state after the delay time
(SS2 time to SOS) and monitors the present position and velocity.
The standard controller lets the Servomotor decelerate to a stop.
4. When the SS2 and SOS functions are released, the Servo Drive goes into the normal state and
stops monitoring the present position and velocity.
The standard controller sets the command velocity to the Servomotor to 600 r/min.
