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).

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

NOTICE
This parameter cannot be adjusted

NOTICE
When
parameter 1-10 Motor Construction
is set to

Range:
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
