Operation Via Terminals
ACTION
See Figure 3.10
Switch S1 (FWD / REV)=open
Switch S2 (Reset)=open
Switch S3 (Start/Stop)=open
Potentiometer R1 (Ref.)=totally CCW
Power-up inverter
Close S2 – Local/Remote
Close S3 – Start / Stop
Turn potentiometer totally CW.
Close S1 – FWD / REV
Open S3 – Start / Stop
The sequence below is valid for the connection 1 (refer to
Section 3.2.5). Inverter must be already installed and powered
up according to Chapter 3 and Section 4.2.
Connections according to Figures 3.4 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 (IxR compensation) at
P136.Increase/decrease the content of P136 gadually 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.
CHAPTER 4 - START-UP
DESCRIPTION
Inverter is ready to be operated.
The command and the reference are
commutaded to REMOTO condition (via
terminals).
Motor accelerates from 0Hz to 3Hz*
(min. frequency), CW direction
* 90rpm for 4-pole motor
The frequency reference is given by the
potentiometer R1.
Motor accelerates up to the the
maximum frequency (P134 = 66Hz)
(3)
Motor decelerates down to 0 rpm (0Hz),
reverses the direction of rotation (CW ⇒
CWW) and accelerates up to the
maximum frequency (P134 = 66Hz).
(3)
Motor decelerates down to 0 rpm.
