Handling Errors and the Error Output
Show Deviation from Command Speed as Error
In certain applications a greater degree of deviation from the
given command speed is unacceptable. Therefore the unit should
be programmed to react by displaying an error.
When the actual speed deviates to the given unnacceptable
degree from the command speed, an error will be displayed.
The error display and reaction can be programmed with
the NE, GES and ERI commands.
The degree of deviation can be programmed:
Command Function Description Example
DEV*) Load Deviation Loads the allowable degree DEV500
of deviation of the actual to
the command speed value.
GDEV Get Deviation Calls up the programmed GDEV
degree of deviation
➔
200
Default Setting: DEV30000 … This degree of deviation cannot
possibly be reached. It represents the
deactivation of deviation error display.
The standard error functions
and the way that these errors
can be rectified are described
in detail in the chapter
“Technical Information”. Aside
from these error functions,
which serve mainly to protect
the motor from being dama-
ged, there is the possibility to
program the unit to handle
application problems.
Delayed Activation of the Error Display
The delay time before displaying an error, during which the
current limiting, over voltage protection or the deviation error
are active can be programmed with the “Delayed Current Error”
function. This makes it possible to ignore short periods of over-
load if, for example, in the acceleration phase the current exceeds
the given limits for a short period of time.
