170 H9 ASD Installation and Operation Manual
Deceleration Time 4
Program ⇒ Special ⇒ Accel/Decel #1 – #4 Settings
This parameter specifies the time in seconds for the output of the ASD to go
from the Maximum Frequency to 0.0 Hz for the #4 Deceleration profile. The
Accel/Decel pattern may be set using
F502. The minimum Accel/Decel time
may be set using F508.
Note: A deceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads. Automatic
Accel/Decel, Stall, and Ridethrough settings may lengthen the
deceleration times.
