6. SERVO MOTOR DRIVING
6 - 74
6.3.5 Directions for use
(1) idx mode operation sequence
(a) Rotation direction specifying indexer
POINT
Be sure to perform a home position return. Executing positioning operation
without home position return will trigger [AL. 90 Home position return incomplete
warning] and "Controlword bit 4 (New set-point)" will be disabled.
The servo motor rotates in a fixed direction to execute positioning to a station.
The following timing chart shows that an operation is started from being stopped at the station No. 0
at servo-on.
1) When using Profile velocity (6081h), Profile Acceleration (6083h), Profile deceleration (6084h)
For the servo motor speed, acceleration time constant and deceleration time constant during
operation, the values set in Profile velocity (6081h), Profile acceleration (6083h), and Profile
deceleration (6084h) are used.
