Parameter Description
4-16 Torque Limit Motor Mode
Range: Function:
Size [ 0 - Enter the maximum torque limit for motor
related 1000.0 % 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 Configuration
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 - 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
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 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:
160.0 [1.0 - Enter the current limit for motor and
% 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
parameter 1-26 Motor Cont. Rated Torque is
changed, parameter 4-18 Current Limit is not
automatically reset to the default setting.

Function:
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 unintended overspeeding
must be avoided. This absolute limit applies to
all configurations and is independent of the
setting in parameter 1-00 Configuration Mode.
Function:
Warnings are shown on the display, programmed
output, or fieldbus.
