Danfoss vlt FC 102 Programming Guide

4-16 Torque Limit Motor Mode
Range: Function:
Size
related*
[ 0 -
1000.0 %]
Enter the maximum torque limit for
motor operation. The torque limit is
active in the speed range up to and
including the nominal motor speed
set in parameter 1-25 Motor Nominal
Speed. To protect the motor from
reaching the stalling torque, the
default setting is 1.1 x the rated
motor torque (calculated value). See
also parameter 14-25 Trip Delay at
Torque Limit for further details.
If a setting in
parameter 1-00 Conguration Mode
to parameter 1-28 Motor Rotation
Check is changed,
parameter 4-16 Torque Limit Motor
Mode is not automatically reset to
the default setting.
4-17 Torque Limit Generator Mode
Range: Function:
100 %* [ 0 -
1000.0 %]
Enter the maximum torque limit for
generator-mode operation. The
torque limit is active in the speed
range up to and including the
nominal motor speed
(parameter 1-25 Motor Nominal
Speed). Refer to parameter 14-25 Trip
Delay at Torque Limit for further
details.
If a setting in
parameter 1-00 Conguration Mode
to parameter 1-28 Motor Rotation
Check is changed,
parameter 4-17 Torque Limit
Generator Mode is not automatically
reset to the default settings.
4-18 Current Limit
Range: Function:
Size
related*
[ 1.0 -
1000.0 %]
Enter the current limit for motor
and generator operation. To protect
the motor from reaching the
stalling torque, the default setting
is 1.1 x the rated motor current (set
in parameter 1-24 Motor Current). If
a setting in parameter 1-00 Congu-
ration Mode to
parameter 1-28 Motor Rotation Check
is changed, parameter 4-16 Torque
Limit Motor Mode to
parameter 4-18 Current Limit are not
automatically reset to the default
settings.
4-19 Max Output Frequency
Range: Function:
Size
related*
[ 1 - 590 Hz]
NOTICE
This parameter cannot be
adjusted while the motor is
running.
Enter the maximum output
frequency value.
Parameter 4-19 Max Output
Frequency species the absolute
limit on the frequency converter
output frequency for improved
safety in applications where
accidental overspeeding must be
avoided. This absolute limit applies
to all congurations and is
independent of the setting in
parameter 1-00 Conguration Mode.
When parameter 1-10 Motor
Construction is set to [1] PM non-
salient SPM, the maximum value is
limited to 300 Hz.
