4-17 Torque Limit Generator Mode
Range: Function:
100.0
%*
[ 0.0 -
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 rated motor speed
(1-25 Motor Nominal Speed). Refer to
14-25 Trip Delay at Torque Limit for further
details.
If a setting in 1-00 Configuration Mode to
1-28 Motor Rotation Check is changed,
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 1-24 Motor Current). If a
setting in 1-00 Configuration Mode to
1-28 Motor Rotation Check is changed,
4-16 Torque Limit Motor Mode to
4-18 Current Limit are not automatically
reset to the default settings.
4-19 Max Output Frequency
Range: Function:
Size
related*
[ 1.0 -
1000.0
Hz]
Enter the maximum output frequency
value. 4-19 Max Output Frequency specifies
the absolute limit on the frequency
converter output frequency for improved
safety in applications where accidental
over-speeding must be avoided. This
absolute limit applies to all configurations
and is independent of the setting in
1-00 Configuration Mode. This parameter
cannot be adjusted while the motor is
running.
When 1-10 Motor Construction is set to [1]
PM non salient SPM the maximum value is
limited to 300Hz.

4-50 Warning Current Low
Range: Function:
0.00 A* [ 0.00 -
par. 4-51

Enter the I
LOW
value. When the motor
current falls below this limit (I
LOW
), the
display reads CURRENT LOW. The signal
outputs can be programmed to produce a
status signal on terminal 27 or 29 and on
relay output 01 or 02. Refer to
Illustration 3.5.

value. When the motor
current exceeds this limit (I

), the
display reads CURRENT HIGH. The signal
outputs can be programmed to
produce a status signal on terminal 27
or 29 and on relay output 01 or 02.
Refer to Illustration 3.5.

Enter the n
HIGH
value. When the motor
speed exceeds this limit (n
HIGH
), the
display reads SPEED HIGH. The signal
outputs can be programmed to produce a
status signal on terminal 27 or 29 and on
relay output 01 or 02. Programme the
upper signal limit of the motor speed,
n
HIGH
, within the normal working range of
the frequency converter. Refer to
Illustration 3.5.
