Controlling the frequency inverter with the ControlBox
The frequency inverter can only be controlled via the ControlBox, if it has not previously been enabled via the
control terminals or via a serial interface (P509 = 0).
If the START key is pressed, the frequency inverter switches to the operating display (selection P001). The
frequency inverter delivers 0Hz or a higher set minimum frequency (P104) or jog frequency (P113).
Parameter set display:
The LEDs indicate in the display the actual operating parameter set and during parameterisation (

P000) the
actual parameter set to be parameterised. In this case, the display appears in binary form.
The parameter set can also be changed during operation via the parameter P100 (control via ControlBox).
Frequency setpoint:
The actual frequency setpoint depends on the setting in the parameters jog frequency (P113) and minimum
frequency (P104). This value can be altered during keyboard operation with the value keys and
permanently stored as the jog frequency in P113 by pressing the ENTER key.
Emergency stop:
By simultaneously pressing the STOP key and the "Change direction key” , an emergency stop can be
initiated.
