Table 113: Range:
Min: 0.1 Hz
Max: 400.0 Hz
Default value: 100 Hz
4-18 Current Limit
Default value: 110%
Parameter type: Range
2-setup: All setups
Conversion index: -
Data type: u_int16
Change during operation: True
Enter the current limit for motor and generator operation.
Parameter 4-18 Current Limit
will be changed automatically if nominal
motor current (
parameter 1-24 Motor Current
) is updated.
Table 114: Range:
Min: 0%
Max: 1000%
Default value: 110%
4-19 Max Output Frequency
Default value: 100.0 Hz
Parameter type: Range
2-setup: All setups
Conversion index: -1
Data type: u_int16
Change during operation: False
Enter the maximum output frequency, which defines the absolute limit on the drive output frequency for improved safety in appli-
cations 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
.
When
parameter 1-10 Motor Construction
is set to 1 of the options enabling PM motor construction, the maximum limit of
parameter
4-19 Max Output Frequency
might be limited by the setting of
parameter 1-40 Back EMF at 1000 RPM
to avoid a too high Back EMF,
which can damage the drive. If
parameter 4-19 Max Output Frequency
is set lower than
parameter 4-14 Motor Speed High Limit [Hz]
,
the value of
parameter 4-14 Motor Speed High Limit [Hz]
is adjusted to the same value as
parameter 4-19 Max Output Frequency
auto-
matically.
Table 115: Range:
Min: 0 Hz
Max: 400 Hz
Default value: 100.0 Hz
4.6.2 4-4* Adjustable Warnings 2
4-40 Warning Freq. Low
Default value: 0 Hz
Parameter type: Range
2-setup: All setups
Conversion index: -1
Data type: u_int16
Change during operation: True
Use this parameter to set a lower limit for the frequency range. When the motor speed drops below this limit, the display reads
SPEED LOW
. Warning bit 10 is set in
parameter 16-94 Ext. Status Word
. The output relay or the digital output can be configured to
indicate this warning. The LCP warning indicator light is not turned on when this parameter set limit is reached.
Table 116: Range:
Min: 0 Hz
Max: 500 Hz
Default value: 0 Hz
4-41 Warning Freq. High
Default value: 100 Hz
Parameter type: Range
2-setup: All setups
Conversion index: -1
Data type: u_int16
Change during operation: True
Use this parameter to set a higher limit for the frequency range. When the motor speed exceeds this limit, the display reads
SPEED
HIGH
. Warning bit 9 is set in
parameter 16-94 Ext. Status Word
. The output relay or the digital output can be configured to indicate
this warning. The LCP warning indicator light is not turned on when this parameter set limit is reached.
Table 117: Range:
