• The ramp time can be adjusted proportionally in C00642

.

• For large machines and high mass inertia values, the ramp time usually has to be increased.

• For small machines, a reduction of the ramp time can speed up the pole position

identification process.

• In some situations it may be helpful to reverse the travel direction (C00643

) for the pole position

identification (e.g. for linear motor at the end stop).

• The "pole position identification 360°" procedure comprises a plausibility check. If the rotor

position determined via the encoder system does not correspond to the controlled output

position:

• the pole position identification procedure is aborted.

• the response parameterised in C00640

(Lenze setting: "Fault") is activated.

• the error message "Pole position identification cancelled" is entered into the logbook of the

controller.

• The preset fault tolerance for the plausibility check can be changed via C00644

.

Parameters for the pole position identification with minimal movement

• The current amplitude can be adjusted proportionally in C00646

.

• For large machines and high mass inertia values or for linear direct drives, the current

amplitude usually has to be increased.

• The Lenze setting "100 %" corresponds to the smaller of the two following values:

 Note!

If the current amplitude is set to 100 % in C00641 >, the device utilisation (Ixt)

monitoring and/or one of the motor monitoring functions may respond and cause the

abort of the pole position identification.
