Note!

For homing, setpoint speeds greater than 30000 rpm are not possible. The speeds

defined for these basic function are internally limited to 30000 rpm.
When the basic function is activated, a start acceleration is considered.

The following applies to the encoderless motor control types :
If the V/f control or sensorless vector control is selected, the basic function "Homing" can

be activated, irrespective of the use of the position controller.

• If no position controller has been selected for the position control in case of V/f

control or sensorless vector control (

C02570

= "1: Phase controller is active"), homing

is only carried out via the speed profile resulting from the homing parameters.

Because of this, the target positions set will only "roughly" be reached.
