Functions of the SimpleBox:
Starting 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.
Stopping the frequency inverter. The output frequency is reduced to the absolute minimum
frequency (P505) and the frequency inverter shuts down.
7-segment
LED display
4-digit
4 permanently displayed underscores (_ _ _ _) indicate readiness for operation if there is no
setpoint. If these underscores are flashing, the frequency inverter is not ready for operation (switch-
on lock, e.g. function “safe pulse block”), or there is, or was, an error. This must first be rectified.
When the frequency inverter is ready for operation any initial value (P104/P113 for keyboard
operation) is indicated by a flashing display. This frequency is immediately displayed on being
enabled.
During operation, the currently set operating value (selection in P001) or an error code (Section 6) is
displayed.
During parameterisation, the parameter numbers or the parameter values are shown.

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. The key
may be locked 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.
OK
Press the “OK” key to store an altered parameter value, or to switch between parameter numbers or
parameter values.
NOTE: If a changed value is not to be stored, the key can be used to exit the parameter
without storing the change.
