Parameter Description
4-17 Torque Limit Generator Mode
Range: Function:
100.0 [ 0.0 - Enter the maximum torque limit for
% 1000.0 %] 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 [ 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
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 [ 1.0 - Enter the maximum output frequency
related 1000.0 value. 4-19 Max Output Frequency specifies
*
Hz] 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.
