Select the control mode.
Select the I/O configuration to preassign the inverter interfaces.
The possible configurations are listed in Sections: Factory setting of the
interfaces (Page 86) and Default setting of the interfaces (Page 88).
Set the applicable motor standard and the inverter supply voltage.
Select the application for the inverter:
• "[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 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]: Setting only for steady-state operation with slow speed changes.
We recommend setting [1] if load surges in operation cannot be
ruled out.
Motor identification:
• [1]: Recommended setting. After an ON command, the inverter
identifies the motor data – and with a new ON command, optimizes
the speed controller.
• [2]: After an ON command, the inverter identifies the motor data at
standstill. 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]: This setting only makes sense after the motor identification [2].
The inverter optimizes the speed controller at the next ON
command.
Calculating the motor parameters: Select "Complete calculation".
