Note
Temperature ranges
Excess temperature of the motor is also monitored and at 155°C (switching threshold for the thermistor) causes
the drive unit to shut down with error message E002.
To determine the stator resistance of the motor, the temperature range 15 … 25°C should not be exceeded.

4.4 Frequency addition and subtraction via operating boxes
(software version 1.7 and above)
If the parameter P549 (PotentiometerBox Function) is set to 4 “Frequency addition” or 5 “Frequency
subtraction”, a value can be added or subtracted via the value keys
or
with the ControlBox or
the ParameterBox.
If the ENTER key
is confirmed, the value is saved in P113. The next time the device is started, the
value will be added or subtracted immediately.
As soon as the inverter is enabled, the ControlBox switches to the operating display. With the
ParameterBox, a change of value can only be made in the operating display. If the ControlBox is
enabled, parameterisation is no longer possible. Enabling via the ControlBox or ParameterBox is also
no longer possible in this mode, even if P509 = 0 and P510 = 0.
Note:
In order to safely activate the ParameterBox in this mode, the STOP key
must be
pressed once.
