Acceleration And Deceleration Characteristics; Setting Acceleration And Deceleration Times - YASKAWA Varispeed L7 Instruction Manual

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. It can be switched over between them
using digital input signals
•
using the automatic accel./decel. time switch over function with a changable switching speed level
•
The display unit and the setting range for the times can be selected between 0.0 sec or 0.00sec.
