NOTICE
Changing
parameter 4-16 Torque Limit Motor Mode
when
parameter 1-00 Configuration Mode
is set to
[0] Speed
open loop
,
parameter 1-66 Min. Current at Low Speed
is
automatically readjusted.
NOTICE
The torque limit reacts to the actual, non-filtered torque,
including torque spikes. This is not the torque that is
seen from the LCP or the fieldbus as that torque is
filtered.
4-17 Torque Limit Generator Mode
Range:
Function:
100 %
*
[ 0 -
1000.0 %]
This function limits the torque on
the shaft to protect the mechanical
installation.
4-18 Current Limit
Range:

*
[ 1.0 -
1000.0 %]
NOTICE
If
[20] ATEX ETR
is selected in
parameter 1-90 Motor Thermal
Protection
, set
current limit to 150%.
This is a true current limit function
that continues in the oversyn-
chronous range. However, due to
field weakening the motor torque
at current limit will drop
accordingly when the voltage
increase stops above the
synchronized speed of the motor.
4-19 Max Output Frequency
Range:
Function:
Size
related
*
[ 1 - 590 Hz]
NOTICE
This parameter cannot be
adjusted while the motor is
running.
NOTICE
Maximum output frequency
cannot exceed 10% of the
inverter switching frequency
(
parameter 14-01 Switching
Frequency
).
Provides a final limit on the output
frequency for improved safety in
applications where overspeeding is
to be avoided. This limit is final in
4-19 Max Output Frequency
Range:
Function:
all configurations (independent of
the setting in
parameter 1-00 Configuration Mode
).
4.5.2 4-2* Limit Factors
4-20 Torque Limit Factor Source
Option:
Function:
Select an analog input for scaling
the settings in
parameter 4-16 Torque Limit Motor
Mode
and
0–100% (or
inverse). The signal levels
corresponding to 0% and 100% are
defined in the analog input scaling,
for example
parameter group 6-1*
Analog Input 1
. This parameter is
only active when
parameter 1-00 Configuration Mode
is in
Speed Open Loop
or
Speed
Closed Loop
