    Already checked. pr45 - 9999(means it takes whatever Pr.44 value is) and when i changed the Pr.44 the drive is not stopping even after giving the group stop command, but when the rest of the drives comes to stop position then it starts deccelerating and finally coming to stop position.

    FR-A800 VFD is in Profibus Communciation with Siemens PLC. Properly Commissioned and has been running since 6 months. But now the Drive is not following the Acceleration and decceleration time (53sec set in drive for ACC and Decc) during start , stop operation. When start PB is pressed, it is reaching setpoint within  5 to 6 seconds irrespective of Accceleration time. When Stop PB is pressed, within 5 to 6 seconds it reaches near zero and again picks up till some rpm and falls back to zero finally following decc. time.
