Derate Reduces the motor speed to decrease the load on
the power section and allowing it to cool down.

*
[50 -
100 %]
Enter the current level (in % of rated output
current for the frequency converter) when
running with reduced motor speed after load
on the frequency converter has exceeded the
allowable limit (110% for 60 s).

14-80 Option Supplied by External 24VDC
Option: Function:

from an external supply.
14-88 Option Data Storage

[0 - 65535 ] This parameter stores information about
options over a power cycle.

in the option configuration is detected.

Freezes the current settings and
prevents unwanted changes when
missing or defective options are
detected.

and is used when modifying the
system configuration. This parameter
setting returns to

after an option change.
3.14.10 14-9* Fault Settings
14-90 Fault Level
This is an array parameter with 26 elements. Each of the bits can
be configured to any of the following options. Use this
parameter to customize fault levels.
Option:
Function:
[0] Off
Use
[0] Off
with caution as it ignores all
warnings and alarms for the selected
source.
[1] Warning
[2] Trip
Changing a fault level from default option
[3] Trip Lock
to
[2] Trip
leads to the
automatic reset of the alarm. For alarms
involving overcurrent, the frequency
converter has a hardware protection that
issues a 3-minute recovery after 2
consecutive overcurrent incidents. This
hardware protection cannot be overruled.
[3] Trip Lock
[4] Trip w. delayed
reset
This option adds a delay between
automatic resets, otherwise it is the same
as option
[2] Trip
. The delay prevents a
situation where reset is attempted
repeatedly for an overcurrent situation.
Hardware protection of the frequency
converter forces the 3-minute recovery time
after 2 consecutive overcurrents (within a
short time window).
