• The maximally effective motor magnetising current is calculated based on the motor data set

in C00084 to C00091.Then the calculated value is internally limited to 98 % of the maximum

current set in C00022

.

• When field weakening is switched on, the actually used maximum effective motor magnetising

current is shown in C00092

, if field weakening is switched off, "0 A" are displayed, as before.

 Note!

If a Lenze motor is used:

The controller is parameterised automatically so that the field weakening works

optimally and there is no danger to the devices.

 Stop!

If an OEM motor is used:

If pulse inhibit is set in the controller, the DC bus is loaded with the voltage that

corresponds to the current speed of the machine.

Since with switched-on field weakening higher speeds can be achieved at a

correspondingly higher rotor voltage of the motor, the DC bus can be loaded to a voltage

higher than the set DC-bus voltage in case of pulse inhibit and a currently high motor

speed and even exceed the maximally permissible voltage of 800 V!

In order to protect the device, either use a brake chopper, or parameterise the speed

monitoring via C00596

and C00607, so that only a maximum motor speed is possible

that could also be reached with Vdc-bus = 800 V without field weakening.
