NB!
Any changes in par.4-13
Motor Speed High Limit [RPM]
will reset the value in par.4-53
Warning Speed High
to the same value as set
in par.4-13
Motor Speed High Limit [RPM]
.
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
Motor Speed Low Limit [Hz]
. Only par.4-11
Motor Speed Low Limit [RPM]
or
par.4-12
Motor Speed Low Limit [Hz]
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
Switching Frequency
).
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.
4-18 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 the
stalling torque, the default setting is 1.1 x the rated motor current (set in par.1-24
Motor Current
).
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
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 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
Configuration Mode
. This parameter cannot be adjusted while
the motor is running.
3.6.3 4-5* Adj. Warnings
Define adjustable warning limits for current, speed, reference and feedback.
