ControlBox functions:
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.
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 used 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. Tin 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. Block 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.
