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 7 A 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
If you wish to change this value before enabling the inverter, change parameter
P121 (Keypad Reference).
(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) In case of having E01 during deceleration, increase the deceleration time through
P101 / P103.
DESCRIPTION
