The parameters below provide the user with the ability to monitor various
operating characteristics of the drive. These parameters are very useful
during commissioning and trouble shooting.
Display of the actual output frequency with a resolution of 0.0125 Hz. The
digital operator will display "noP" or "LS" if the enable (terminal 16) or the
direction of rotation (terminal 14 or 15) are not energized (see CP.3). The
rotation of the motor is indicated by the sign.
Output frequency 18.3 Hz, rotation forward
Examples:
Output frequency 18.3 Hz, rotation reverse

Inverter status
display
The status display shows the actual working conditions of the inverter.
Possible displays and their meanings are:
"no Operation" control release (terminal 16) signal removed,
modulation off, output voltage = 0 V, drive is disabled.
" Low Speed " no direction signal at F or R (terminal 14 or 15),
modulation off, output voltage = 0 V.
Display of the actual set frequency. The indication is done in the same manner
as at CP.1. For control reasons the set frequency is displayed even if control
release or direction of rotation are enable. If no direction of rotation is set,
the set frequency for clockwise rotation (forward) is displayed.

From the factory, the frequency inverter is supplied without pass-
word protection, this means that all parameters can be adjusted.
After programming, the unit can be protected against unauthorized
access thus preventing the values from being changed.
