NOTE!
The lastfrequencyreference (speed)value setvia the
and keys is saved.
Ifyou wishtochange this valuebeforeinverter enabling,change
parameterP121- Keypad Reference.
NOTES!
(1)
Ifthe direction ofrotationofthe motorisnotcorrect,switchoff
the inverter. Wait at least for 10 minutes to allow complete
capacitordischargeandthen swapanytwo wiresatthemo-
tor output.
(2)
If the acceleration current becomes too high, mainly at low
frequencies,setthetorqueboost(IxRcompensation)atP136.
Increase/decrease the content of P136 gradually until you
obtain an operation with constant current over the entire
frequencyrange.
Forthe caseabove, refer toparameterdescriptioninchapter
6.
(3)
If E01 fault occurs during deceleration, increase the
deceleration time at P101 / P103.

Power-up the inverter
Press the key
Press the key and hold it
depressed until 60 Hz is reached
Press the key
Press
the key
Press

Release the key
Inverter is ready to be operated
Motor accelerates from 0 Hz to 3 Hz

direction ofrotation
(1)
Motor accelerates up to 60 Hz
(**)
(2)
Motor decelerates
(3)
down to 0 rpm and
then reverses the direction of rotation
CW

CCW accelerating back to 60 Hz
Motor decelerates down to 0 rpm
Motor accelerates up to JOG frequency
given by P122.
Ex:
P122 = 5.00 Hz
Reverse (CCW)
Motor decelerates down to 0 rpm

Thesequence belowis validfor the connection 1 (refer to item
3.2.6). Inverter must be already installed and powered up
according to chapter 3 and item 5.2.
Connections according to figure 3.6.
