Description

Motor current
Iref (A) =

Enter here the reference current of the motor. Normally a value
of maximum 150% of the nominal current of the motor is used.
Any lower value can be set.

If Im>Iref 0=trip
1=dec. 2=ignore ?

Set here the reaction of the drive when the motor current

exceed the set reference value

REF

Set:

•

if you want to trip the drive

•

if you want to reduce the output frequency

to keep the

motor current lower than the reference current

•

if you want to ignore the information. In this case the

maximum current of the inverter will be available for the motor.
The information that the current

> I

REF

can be allocated to one

of the output relay (see menu C).

RI-compensation
(V) =

The resistance

of the motor winding is source of a voltage drop

proportional to the motor current

. The

voltage will be added

to the output voltage

to obtain the nominal torque over the

entire frequency range. This function is mainly used when
operating at the lower part of the range.

The value can be set between 0 and 38 V.

Acceleration time
(s) =

The

acceleration

time is set in seconds, between 1 to 255.

This is the acceleration time needed to reach the full speed of
the motor. If the set speed is the half of the full speed, the time
to reach this speed will be the half of the acceleration set time.
This value is a minimum and can’t be reduced in menu D.

Deceleration time
(s) =

The

deceleration

time is set in seconds, between 1 to 255.

This is the deceleration time needed to reach zero speed from
the full speed of the motor. If the set speed is the half of the full
speed, the time to stop will be the half of the deceleration set
time. This value is a minimum and can’t be reduced in menu D.

Freq ctrl source
0=PC560 1=T.Bl.?

At this step you can set if you want to control the output
frequency of the drive, respectively the motor speed using the
K

or the T

ERMINAL

LOC

X2.

•

Enter

for the

control. You will here set the speed

using the function

2ndF F

followed by the value of the

frequency

in Hz

the

speed

in RPM depending on your

setting of the displayed unit - see

Speed display units

above.

•

Enter

for the

ERMINAL

LOC

control.

The connections are

described in paragraph

“The Speed Reference Input”

page 17.

Default frequency
(Hz) =

In case of selection of the

Freq. ctrl source

selection from the

frequency control, the value entered or shown here will

be taken as speed reference input when the inverter is being
turned ON. In programming mode you can change the value just
by entering a new one. Here again, the input must be in Hz,
input in RPM is not allowed and will lead to a mis-setting.
In operating mode you can record here the last input made by

2ndF F

, using the quick recording process

2ndF J.

Minimum frequency
(Hz) =

Enter the minimum allowed operating frequency in Hz. Input in
RPM is here not allowed and will lead to a mis-setting.

•

Any reference input lower than this value will be ignored.

•

This low limit is active when the

Freq. ctrl source

has been

selected either from the
