Acceleration and Deceleration Characteristics
Setting Acceleration and Deceleration Times
The acceleration time indicates the time to increase the speed from 0% to 100% of the maximum speed set in
E1-04. The deceleration time indicates the time to decrease the speed from 100% to 0% of E1-04.
Four separate acceleration and deceleration times can be set. They can be switched over between using:
digital input signals
•
the automatic accel./decel. time switch over function with a changeable switching speed level
•
The display unit and the setting range for the times can be selected between 0.0 sec. or 0.00 sec.
