Function:
[ 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 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.
Function:
[ 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 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.
Function:
[ 1.0 - 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 Configu-
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.

Function:
NOTICE
[ 1 - 590 Hz]
This parameter cannot be
adjusted 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.
When parameter 1-10 Motor
Construction is set to [1] PM non-
salient SPM, the maximum value is
limited to 300 Hz.
