inverter to increase. So when the f unction of over-voltage stall prevention is
started, if the DC voltage of the inverter becomes too high, the inverter will
stop decelerating till the voltage at DC decreases below the set value, then the
inverter will go on to decelerate and the ramp-down time will be extended
automatically.
When the inverter is in ramp-up, due to overload or too short ramp-up time,
the output current of the inverter will go up quickly and exceed the set
standard level. When this happens, the inverter will stop accelerating. When
the current returns under its set value, the inverter will go on to accelerate.
CD121 Stall Prevention Level at Ramp-up
Set Range
:
0—200% Unit: 1% Factory Setting: 150
100% current is the rated current of the motor. When this parameter is set to 0,
the stall prevention f unction is invalid.
When the inverter is running at constant speed, due to load fluctuation and
other reasons, the current will increase. When the current exceeds its set
standard value, the inverter will lower the output frequency. When the output
current returns to its normal range, the inverter will accelerate again to its set
frequency.
CD122 Stall Prevention Level at Constant Speed
Set Range: 0—200%
Unit: 1% Factory Setting: 0
100% current is the Rated Current of the motor. When this parameter is set to
0 the stall prevention f unction is invalid.
Refer to CD120.
CD123 Stall Prevention Level at Deceleration
Set Range:0~232%
Unit:1% Factory Setting:0
