Acceleration and Deceleration Characteristics
îš‹ Setting Acceleration and Deceleration Times
The acceleration time indicates the time to increase the output frequency from 0% to 100% of the maximum
output frequency (E1-04). The deceleration time indicates the time to decrease the output frequency from
100% to 0% of (E1-04). The accel./decel. times 1 are used with the factory setting, the accel./decel. times 2 to
4 can be selected using a multifunction digital input. The accel./decel. times 1 are used with if no other accel./
decel.time has been selected by a multi-function digital input.
