In order to have an indication that the drive is in a "special" operating state when
the error display is suppressed, this is displayed in parameter
state and the statusword.

Warnings

Additionally to the errors which always lead to drive stop, the drive can display
warnings. Warnings have no reaction to the drive. The existance of a warning can

mode.
Note
By UP or LT ready, the "fault" bit in the statusword is not set as long as the
auto retry time UP is running
If the setting of pn84[1] is "0: no time limit", the "fault" bit is not suppressed.
The UP error can also be reset via a hardware reset during the auto-retry
time.
With this setting the UP error is reset at every hardware reset. The reduced
precharge time is not effective when precharging after the "Manual Reset".
If this bit is not activated, the error UP cannot be reset when auto-retry UP is
permanently activated (auto-retry UP time = 0: no time limit), since the error
remains present until the mains voltage is switched back to the device.
