Drives

[twistertime]

Have a powerflex 700 and I am having issues with the stopping control of the drive.If I depress the Stop button, it decels with DC braking and stops within the 2 sec. decel time, no faults and all is as it should be.The next time I depress the Stop Button, it coasts to a stop after about 10 seconds.It is always every other time that it coasts. If I watch the HIM, one time it states DC braking when all is well and then the drive goes to Not Enabled when the drive is operating properly. The next time I depress the stop button after a run condition , the drive says Stopped  for about 3 seconds then the display reads Not Enabled but the drive is still coasting to a stop. There are never any drive faults or alarms. This has never been right and has acted this way since the install.If I look at drive status 1, the Active bit goes out immediately when the drive coasts yet the active bit stays on until the drive is Not Enabled after a good stop. Any help would be appreciated.

Is the drive being controlled either from a network or with digital inputs or strictly from the HIM?

The drive is being controlled by 2 digital inputs. A run bit to digital 2   (362) and is programmed as run forward and an enable bit to digital input 6 ( 366)( this is a 3 sec delayed out from a pilz relay that keeps the drive enabled after a stop).
