Function:
0 - Enter the maximum torque limit for motor
operation. The torque limit is active in the
speed range up to and including the rated
motor speed set in 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 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,
4-16 Torque Limit Motor Mode is not automat-
ically 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 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.
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 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.
Function:
1 - 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.
