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
must = 0.
a) To switch off (block) the frequency inverter during operation. The output frequency is reduced to the
absolute minimum frequency (P505) and the frequency inverter shuts down.
b) During parameterisation, the operating value display P000 (starting display after mains ON) can be
called up from any parameter.
7-segment
LED
display
a) Shows the current operating value set during operation (selection in P001) or an error code.
b) During parameterisation, the parameter numbers or the parameter values are shown. When
switched off, but operational, four dashes "_ _ _ _" are displayed or, if a setpoint frequency > 0Hz is
set in P113, this value will flash.

a) 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.
b) To cancel a value changed during parameterisation mode, press this key.
a) Press key to increase the frequency.
b) During
parameterisation, the parameter number or parameter value is increased
a) Press the key to reduce the frequency.
b) During
parameterisation, the parameter number or parameter value is reduced.
a) Press "ENTER" to store a changed parameter value, or to switch between parameter number and
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.
b) When operating with the keyboard control, the actual frequency value can be saved in parameter
P113 Jog frequency. This is then the starting value when the START key is used to enable.
