CHAPTER 5 - START-UP
NOTE!
The inverter always stores the last speed reference value set through the keypad.
Therefore, if you want to change this value before enabling the inverter use the
parameter
P121
- Keypad Speed Reference.
NOTES!
(1)
P401 maximum value is 1.8 x P295 for model 4.2 A/500-600 V and 1.6 x P295
for models 7A and 54 A/220-230 V; 2.9 A and 7 A/500-600 V; 107 A, 147 A and
247 A/500-690 V; 100 A, 127 A and 340 A/660-690 V.
(2)
The last speed reference value set via the
and
keys is saved.
If you wish to change this value before enabling the inverter, change parameter
P121
(KeypadReference).
(3)
If the direction of rotation of the motor is inverted, power the
inverter
down, waits
10 minutes for the complete discharge of capacitors and interchange any two
motor output cables.
(4)
Incase of having E01duringdeceleration, increasethe decelerationtime through
P101 / P103.
