Parameter Description
4-17 Torque Limit Generator Mode
Range: Function:
100 [ 0 - Enter the maximum torque limit for generator
% 1000.0 mode operation. The torque limit is active in
*
%] the speed range up to and including the rated
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 Configuration
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 [ 1.0 - Enter the current limit for motor and
related 1000.0 generator operation. To protect the motor
*
%] from reaching the stalling torque, the
default setting is 1.1 x the rated motor
torque (calculated value). If a setting in
parameter 1-00 Configuration Mode to 1-26
Motor Cont. Rated Torque is changed,
4-18 Current Limit is not automatically reset
to the default setting.

while the motor is running.
Enter the maximum output frequency value.
Parameter 4-19 Max Output Frequency
specifies 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 configurations and is
independent of the setting in
parameter 1-00 Configuration Mode.
NOTICE
When parameter 1-10 Motor Construction is set to [1] PM,
non-salient SPM, the maximum value is limited to 300 Hz

Define adjustable warning limits for current, speed,
reference and feedback.
