Procedure without application class or for the application class [0]: Expert
Select the control mode.
Select the I/O configuration to preassign the inverter interfaces.
Set the applicable motor standard and the inverter supply voltage.
Application:
● "[0] Load cycle with high overload for applications requiring a high dynamic performance,
e.g. conveyor systems.
● "[1] Load cycle with low overload ..." for applications that do not require a high dynamic
performance, e.g. pumps or fans.
● [6], [7]: Load cycles for applications with encoderless 1FK7 synchronous motors.
Select your motor.
Enter the motor data according to the type plate of your motor.
If you have selected a motor based on its article number, the data has already been entered.
Set the most important parameters to suit your application.
Material damage caused by unexpected acceleration of the motor
Depending on the Power Module, the inverter sets the minimum frequency p1080 to 20% of
the maximum frequency. Also for setpoint = 0, the motor accelerates for p1080 > 0 to the
minimum frequency after switching on the motor. An unexpected acceleration of the motor
can cause material damage.
● If the application requires a minimum frequency = 0, set p1080 = 0.
Application:
● [0]: In all applications that do not fall under [1] ... [3]
● [1]: Applications involving pumps and fans
● [2]: Applications with short ramp-up and ramp-down times. However, this setting is not
suitable for hoisting gear and cranes.
● [3]: Setting only for steady-state operation with slow speed changes. We recommend
setting [1] if load surges in operation cannot be ruled out.
