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:
0 Hz
*
[1 - 1000 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 accidental overspeed-
ing must be avoided. This absolute limit applies to all configu-
rations 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.
NB!
Not visible in display, only in VLT Motion Control Tool, MCT 10.
Warnings are shown on display, programmed output or serial bus.
4-50 Warning Current Low
Range:
Function:
0.00A
*
[0.00 - par. 4-51 A]
Enter the I
LOW
value. When the motor current falls below this
limit (I
LOW
), the display reads CURRENT LOW. The signal out-
puts can be programmed to produce a status signal on terminal
