Execute pole position identification 360°

Preconditions for the execution

• A synchronous motor has been selected.
• No other identification is active.
• No error has occurred.

Danger!

The machine must not be braked or blocked during the pole position identification! For this

reason, the pole position identification is not permitted for hanging loads!
During the pole position identification the rotor aligns itself. The motor shaft moves by

max. one electrical revolution which causes the corresponding movement of the connected

mechanical components!

Stop!

Check the correct parameterisation of the max. motor current monitoring before

carrying out the pole position identification to prevent the motor from being

permanently damaged.

Maximum current monitoring

( 303)

Note!

By means of controller inhibit, the procedure started can be cancelled anytime, if

required, without carrying out a change in

C00926

.

If the pole position identification is aborted, the response parameterised in

C00643/1

is

activated (Lenze setting: "Fault").

• If this behaviour is not wanted, deactivate the monitoring by selecting "0: No

response" in

C00643/1

.
