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.
