Display readout states
Display mode
In normal operation, one item of operating data can
be displayed continuously at the operator
’
s own
choice. By means of the [+/-] keys the following
options can be selected in Display mode:
-
Output frequency [Hz]
-
Output current [A]
-
Output voltage [V]
-
Intermediate circuit voltage [V]
-
Output power [kW]
-
Scaled output frequency f

Menu mode
In order to enter the Menu mode [QUICK MENU]
+ [+] must be activated at the same time.
In Menu mode, most of the frequency converter
parameters can be changed. Scroll through the
parameters using the [+/-] keys. While scrolling in the
Menu mode proceeds, the parameter number will flash.
The display shows that the setting in parameter
102
Motor power P
M,N
is 0.75. In order to change
the value of 0.75, [CHANGE DATA] must first
be activated; the parameter value can then be
changed using the [+/-] keys.
If for a given parameter the display shows three
dots at the right, it means that the parameter
value has more than three digits. In order to see
the value, activate [CHANGE DATA].
The display shows that in parameter 128

Quick menu
Using the [QUICK MENU] key, it is possible to access
the 12 most important parameters of the frequency
converter. After programming, the frequency converter
is in most cases ready for operation. When the
[QUICK MENU] key is activated in Display mode, the
Quick menu starts. Scroll through the quick menu
using the [+/-] keys and change the data values by
first pressing [CHANGE DATA] and then changing
the parameter value with the [+/-] keys.

Hand Auto
During normal operation the frequency converter is
in Auto mode, where the reference signal is given
externally, analog or digital via the control terminals.
However, in Hand mode, it is possible to give the
reference signal locally via the control panel.
