• 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:

Stop!
If there is no temperature monitoring in the motor and/or the I 2 xt motor monitoring and
the maximum current monitoring are not parameterised correctly, the motor may be
permanently damaged when the current amplitude is set too high (e.g. to the maximum
value)!
