4-14 Motor Speed High Limit [Hz]
Range:
Function:
50/60.0
Hz*
[par. 4-12 - par. 4-19 Hz]
Enter the maximum limit for motor speed. The Motor Speed High Limit can be set to correspond to
the manufacturer’s recommended maximum of the motor shaft. The Motor Speed High Limit must
exceed the in par.4-12
or
will be displayed depending on other parameters in the Main
Menu and depending on default settings dependant on global location.
NB!
Max. output frequency cannot exceed 10% of the inverter switching frequency (par.14-01
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
. 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
for further details.
If a setting in par.1-00
is changed, par.
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
). Refer to par.
for further details.
If a setting in par.1-00
is changed, par.
is not automatically reset to the default settings.
4-18 Current Limit
Range:
Function:
110 %*
[1 - 1000 %]
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 torque (calculated value). If a setting in
par. 1-00 to par. 1-26 is changed, par. 4-18 is not automatically reset to the default setting.
4-19 Max Output Frequency
Range:
Function:
100.0 Hz* [1.0 - 1000.0 Hz]
Enter the maximum output frequency value. par.4-19
specifies the absolute
limit on the frequency converter output frequency for improved safety in applications where acci-
dental over-speeding must be avoided. This absolute limit applies to all configurations and is
independent of the setting in par.1-00
. This parameter cannot be adjusted while
the motor is running.
2.6.3 4-5* Adj. Warnings
Define adjustable warning limits for current, speed, reference and feedback.
