)
Note:
To maintain inverter permanently
in remote mode, set
P220
=
1.
If the inverter is switched off and
afterwards switched on, it
will
now operate in local mode
because P220 = 2 (factory
setting). This setting means
that the local/remote selection
source is via keypad and the
default mode (that is the mode
when the inverter is switched
on) is local. For further
information refer to the
description of P220 in chapter 6
Motor accelerates from 0 Hz to 3 Hz
(*)
(minimum frequency), CW direction
(1)
The frequency reference is given by the
potentiometer R1
Motor accelerates up to the maximum
frequency (P134 = 66 Hz)
(2)
Motor decelerates
(3)
down to 0 rpm (0
Hz), reverses the direction of rotation
(FWD/REV) accelerating back up to the
maximum frequency (P134 = 66 Hz)
Motor decelerates
(3)
down to 0 rpm
NOTES!
(1)
If the direction of rotation of the motoris not correct, switch
off the inverter. Wait 10 minutes to allow a complete
capacitor discharge and swap any two wires at the motor
output
.
(2)
If the acceleration current becomes too high, mainlyat low
frequencies, set the torque boost (IxR Compensation) at
P136.
(*)
90 rpm for 4-pole motor.
