CHAPTER 5 - START-UP
5.3.2 Start-up
Operation Via
Terminals
Connections according to figures 3.6 and 3.10.
NOTES!
(1) If the direction of roation of the motor rotation is not correct, switch
off the inverter. Wait 10 minutes to allow a complete capacitor
discharge and the swap any two wires at the motor output.
(2) If the acceleration current becomes too high, mainly at low
frequencies, set the torque boost (I x R compensation) at
P136.Increase/decrease the content of P136 gradually until you
obtain an operation with constant current over the entire frequency
range. For the case above, refer to Parameter Description in
Chapter 6.
(3) If E01 fault occurs during deceleration, increase the deceleration
time at P101 / P103.
(4) Function 2 configuration is not possible on CFW-10 Clean
version.
The sequence below is valid for the Connection 2 (refer to Section
3.2.6). Inverter must be already installed and powered up according
to Chapter 3 and Section 5.2.
ACTION HMI DISPLAY DESCRIPTION
See Figure 3.10
Switch S1 (FWD/REV) = Open
Switch S2 (Local/Remote) = Open
Switch S3 (Start/Stop) = Open
Potentiometer R1 (Ref.) = Positioned
totally to the left (counterclockwise)
Power-up inverter
Close S2 – Local/Remote
Close S3 – Start / Stop
Turn potentiometer clockwise until the
end
Close S1 – FWD/REV
Open S3 – Start/Stop
Inverter is ready to be operated
The command and the reference are
commutaded to REMOTO condition
(via terminals).
Motor accelerates from 0 Hz to 3 Hz*
(min. frequency), CW direction
(1)
* 90 rpm for 4-pole motor
The frequencyreference is given by
the potentiometer R1
Motor accelerates up to the the
maximum frequency (P134 = 66 Hz)
(2)
Motor decelerates
(3)
down to 0 rpm
(0 Hz), reverses the direction of
rotation (CW CWW) and
accelerates up to the maximum
frequency (P134 = 66 Hz)
Motor decelerates
(3)
down to 0 rpm
