4-16 Torque Limit Motor Mode
Range: Function:
110.0 %* [0.0 - 1000.0 %] 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 par.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 (calcu-
lated value). See also par.14-25
Trip Delay at Torque Limit
for further details.
If a setting in par.1-00
Configuration Mode
to par.1-28
Motor Rotation Check
is changed, par.
4-16
Torque Limit Motor Mode
is not automatically reset to the default setting.
4-17 Torque Limit Generator Mode
Range: Function:
100.0 %* [0.0 - 1000.0 %] 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 (par.1-25
Motor Nominal Speed ). Refer to par.
14-25 Trip Delay at Torque Limit for further details.
If a setting in par.1-00 Configuration Mode to par.1-28 Motor Rotation Check is changed, par.
4-17 Torque Limit Generator Mode is not automatically reset to the default settings.
4-18 Current Limit
Range: Function:
110.0 %* [1.0 - 1000.0 %] Enter the current limit for motor and generator operation. To protect the motor from reaching stall-
ing torque, the default setting is 1.1 x the rated motor current (set in par. 1-24). If a setting in par.
1-00 to par. 1-26 is changed, par.4-16
Torque Limit Motor Mode
to par.4-18
Current Limit
are not
automatically reset to the default settings.
4-19 Max Output Frequency
Range: Function:
100.0 Hz* [1.0 - 1000.0 Hz] Enter the maximum output frequency value. par.4-19 Max Output Frequency specifies the absolute
limit on the adjustable frequency drive 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 par.1-00
Configuration Mode . This parameter cannot be adjusted while
the motor is running.
