6.8 Adjusting the rotor position

When is a rotor position adjustment required?

ƒ A synchronous non−Lenze motor is used. The motor used is not

included in GDC.

ƒ Another encoder was mounted to the motor later on.

ƒ A defective encoder was replaced.

 Note!

Only use single−pole resolvers or SinCos encoders (single−turn or

multi−turn).

ƒ Inhibit the controller.

ƒ Unload the motor mechanically.

– Disconnect the motor from the gearbox/machine.

– If necessary, remove toothed lock washers, gears, etc. from the motor

shaft.

– If necessary, support the holding torques provided by mounted motor

brakes by means of locking devices.

ƒ Deactivate the "safe torque off" function so that the motor can be

energised for the motor pole angle adjustment.

ƒ Release the holding brake (if available).

ƒ Adjust the current controller (see chapter "Current controller

adjustment").

ƒ Check resolver polarity.

ƒ Set C0006 = 3.

– For carrying out a rotor position adjustment, a synchronous motor

must be selected.
