2.2.1.2 Operation
Switching on the frequency inverter. The frequency inverter is now enabled with the set jog frequency
(P113). A preset minimum frequency (P104) may at least be provided. Parameter >Interface< P509 and
P510 must = 0.
Switching off the frequency inverter. The output frequency is reduced to the absolute minimum
frequency (P505) and the frequency inverter shuts down.

Operating mode Display Comments
Ready for operation
without setpoint present
Display of 4 static underscores.
If the underscores flash slowly:
the frequency inverter is not ready for operation (e.g.:)
 Starting disabled:
Function “Safe pulse block“ or
Fast stop active
 enable signal before the frequency inverter is ready for
operation.
Ready for operation
with setpoint present
Numbers flash slowly:
A starting setpoint (P104 / P113 in keyboard operation)
(e.g.: 5.3Hz) is indicated. This frequency is immediately
used on being enabled.
In operation Display of actual frequency.
In case of fault Display of an actual and active error message.
Slow flashing of the display indicates that the fault is no
longer present and the error message can be
acknowledged.
Parameterisation Display of parameter number or parameter value.
1. Parameter group
(e.g.: Motor data (P2 - -))
2. Parameter number
(e.g.: Nominal speed (P202))
3. Parameter value
(e.g.: 1360min -1 ))
LEDs

The LEDs indicate the actual operating parameter set in the operating display (P000) and the actual
parameter set being parameterised during parameterisation. In this case the display is coded in binary
form.

The motor rotation direction changes when this key is pressed. "Rotation to the left" is indicated by a
minus sign.
Attention! Take care when operating pumps, screw conveyors, ventilators, etc. → You can disable the
key with parameter P540.
Press key to increase the frequency. During parameterisation, the parameter number or parameter
value is increased
Press the key to reduce the frequency. During parameterisation, the parameter number or parameter
value is reduced.
Press "ENTER" to store an altered parameter value, or to switch between parameter number or
parameter value.
NOTE: If a changed value is not to be stored, the key can be used to exit the parameter without
storing the change.
