3.2.3 Control
The frequency inverter can only be controlled via the control panel, if it has not been previously
enabled via the control terminals or via a serial interface (P509 = 0 and P510 = 0).
Once the control panel has been mounted on the frequency inverter and provided with power, the
display briefly shows the type of device and the rated power. After this the display for readiness to
operate is shown.
If the Start key is pressed, the frequency inverter changes to the operating display (selection P001).
The frequency inverter supplies 0 Hz or the minimum frequency (P104) or jog frequency (P113) which
has been set.
Parameter set display
In the operating display (P000) the parameter set display shows the actual parameter set and for
parameterisation (≠ P000), the parameter set which is being parameterised.
For control of the frequency inverter via the control panel, the parameter set can be switched over via
P100 even during operation.
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 ▼ and permanently stored in P113 as the jog frequency by pressing the OK key.
Emergency stop:
By simultaneously pressing the ▼ und ▲ keys, a quick stop can be initiated.
