NOTE!
The last frequency reference value set via the and keys is saved.
If youwishto changethis value beforeenablingtheinverter, change parameter
P121
(Keypad Reference).
OBSERVATIONS:
(1)
If the rotation direction of the motor is not correct, switch off the inverter.
Wait 10 minutes to allow a complete discharge of the capacitors and then
swap any two wires at the motor output.
(2)
If the acceleration current becomes too high, specially at low frequencies
(< 15 Hz), adjust the Torque Boost at
P136
.
Increase/decrease the content of
P136
graduallyuntil you obtain an
operation with constant current over the entire frequencyrange.
Refer to P136 in chapter 6.
(3)
If E01 fault occurs during deceleration, increase the deceleration time at
P101
/
P103
