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.
Factory setting of the interfaces (Page 88)
Default setting of the interfaces (Page 91)
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.
Select your motor.
Enter the motor data according to the rating 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.
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/lifting gear.
● [3]: Applications involving pumps and fans with optimized efficiency. The setting only makes
sense for steady-state operation with slow speed changes. We recommend setting [1] if
load surges in operation cannot be ruled out.
● [5]: Applications with high breakaway torques, e.g. extruders, mills and mixers
Motor identification:
● [1]: Recommended setting. Measure the motor data at standstill and with the motor rotating.
The inverter switches off the motor after the motor data identification has been completed.
● [2]: Measure the motor data at standstill. The inverter switches off the motor after the motor
data identification has been completed.
Recommended setting for the following cases:
– You have selected "Speed control" as control mode, however the motor cannot freely
rotate, e.g. for mechanically limited traversing sections.
– You have set "V/f control" as control mode.
● [3]: Measure the motor data while it is rotating. The inverter switches off the motor after the
motor data identification has been completed.
