Control with the SimpleBox / ControlBox

The frequency inverter can only be controlled via the SimpleBox, if it has not previously been enabled via the
control terminals or via a serial interface (P509 = 0 and P510 = 0).
As well as this, with the series SK 500E and SK 700E no technology unit (SK TU3-PAR or SK TU1-PAR) may be
plugged into the inverter.
If the "START" key is pressed, the frequency inverter in the operating display changes (selection P001). The
frequency inverter supplies 0Hz or the minimum frequency (P104) or jog frequency (P113) which has been set.
The following illustration is for the SimpleBox and applies accordingly for the ControlBox.

Parameter set display:
The LEDs indicate the actual operating parameter set in the operating display (P000) and the current parameter set
being parameterised (



P000). In this case, the display appears in binary form.

The parameter set can also be changed during operation via the parameter P100 (control via SimpleBox).

Frequency setpoint:
The current 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 in P113 as the jog frequency by pressing the ENTER key.

Frequency addition (only SK 5xxE):
If the parameter “PotentiometerBox Function” (P549) has been set to function {4}”Frequency addition” or function
{5} “Frequency subtraction”, as of software version 1.7 of the inverter a setpoint can be added via the Box, even if
enabling and other setpoints are provided from another source (control terminals, BUS).
However, after the drive unit has been shut down, this additive setpoint is reset to zero.
By pressing the ENTER key however, the set value is permanently stored in parameter P113 as the jog frequency,
and continues to be available as a setpoint value on re-enabling after shutdown.

Emergency stop (only SK TU3-CTR):

By simultaneously pressing the STOP key

and the "Change direction key”

, an emergency stop can be

initiated.

Information for the SimpleBox (SK CSX-3x)
No technology unit (SK TUx-PAR) may be plugged in if SK 500E and SK 700E series inverters are used.
Otherwise, communication errors can be expected.
