Change: In real time
Value Range:
0.0s to 6500.0s
Description
The acceleration time indicates the time required for the output frequency to rise
from 0 to F0‑25 (acceleration/deceleration base frequency). It is usually
determined by the rise of the frequency reference signal. The frequency reference
rise rate must be limited to prevent overcurrent during acceleration of the motor.
The acceleration time must be set to ensure that the acceleration current is below
the overcurrent capacity of the AC drive to avoid that the AC drive trips due to
overcurrent stall.

Description
The deceleration time indicates the time required for the output frequency to
decrease from F0‑25 (acceleration/deceleration base frequency) to 0. The
deceleration time is usually determined by the fall of the frequency reference
signal. The frequency reference drop rate must be limited to prevent overvoltage
during deceleration of the motor.
The deceleration time must be set to ensure that the smoothing circuit voltage
will not be excessive to avoid that the AC drive trips due to overvoltage stall.
