VLT® Flow Drive FC 111
Programming Guide
Table 113: Range:
Min: 0.1 Hz
4-18 Current Limit
Default value: 110%
Conversion index: -
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%
4-19 Max Output Frequency
Default value: 100.0 Hz
Conversion index: -1
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
4.6.2 4-4* Adjustable Warnings 2
4-40 Warning Freq. Low
Default value: 0 Hz
Conversion index: -1
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
4-41 Warning Freq. High
Default value: 100 Hz
Conversion index: -1
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.
