Data readout:
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 variable frequency drive
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 Motor thermal
protection the selection made is Thermistor trip [2].
