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.
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
– 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.
