rated motor speed (par. 1-25). To protect the mo-
tor from reaching the stalling torque, the default
setting is 1.6 x the rated motor torque (calculated
value). If a setting in par. 1-00 to par. 1-26 is
changed, par. 4-16 to 4-18 are not automatically
reset to the default settings.
Changing par. 4-16 Torque Limit Motor
Mode when par. 1-00 is set to Speed
open loop [0], par. 1-66 Min Current at
Low Speed is automatically readjus-
ted.
4-17 Torque Limit Generator Mode
Value:
0.0 - Variable Limit %
Function:
Sets the torque limit for generator mode opera-
tion. The torque limit is active in the speed range
up to the rated motor speed (par. 1-25). See il-
lustration for par. 4-16 as well as par. 14-25 for
further details.
4-18 Current Limit
Value:
0.0 - Variable Limit %
Function:
Sets the current limit for motor operation. To pro-
tect the motor from reaching the stalling torque,
the default setting is 1.6 x the rated motor torque
(calculated value). If a setting in par. 1-00 to par.
1-26 is changed, par. 4-16 to par. 4-18 are not
automatically reset to the default settings.

MG.33.B7.02 - VLT is a registered Danfoss trademark
Function:
Provides a final limit on the drive output frequency
for improved safety in applications where you
want to avoid accidental over-speeding. This limit
is final in all configurations (independent of the
setting in par. 1-00).
NB!
Max. output frequency cannot exceed
10% of the inverter switching frequen-
cy (par. 14-01).
Par. 4-19 cannot be adjusted while the motor is
running.

Function:
Select an analog input for scaling the settings in
par. 4-16 and 4-17 from 0% to 100% (or inverse).
The signal levels corresponding to 0% and 100%
are defined in the analog input scaling, e.g. par.
group 6-1*. This parameter is only active when
par. 1-00 Configuration Mode is in Speed Open
Loop or Speed Closed Loop.
