3.5.4 4-5* Adjustable Warnings
Use these parameters to adjust warning limits for current,
speed, reference, and feedback.
Warnings are shown on the LCP and can be programmed
to be outputs or to be read out via fieldbus in the

Only available in flux control
principle.
Enter the timeout period during
which a deviation defined in
parameter 4-44 Motor Speed Monitor
Max is allowable. The timer for this
parameter is reset if the deviation
stops exceeding the value in
parameter 4-44 Motor Speed Monitor
Max.
Function:
NOTICE
The parameter is only
applicable for 8.XX.
Select the time interval at which
the connections between the motor
and the drive is checked, when the
motor is stopped. The motor check
is performed at a specified interval,
unless the motor is started in
between.
The motor time constant (x10) is
used as the time interval to check
the motor.
