Siemens 1FT5 with Hall/Tach support

These old Siemens 1FT5 motors typically have 3 separate feedbacks that need to be tested and aligned; Hall effects, 3-phase AC tach, and incremental encoder. All except the AC tach can be tested using the generic incremental selection on the TI-5000JX. The AC tach has to be tested with an oscilloscope for proper alignment. 

The Halls and tach are tested using the TI-5055 test cable. The Hall effects should align as follows, using the toggle pulse (H/L) as the guide for alignment:

                        H1       H2       H3

       +U-V        H/L      H         L

      +U-W        L          H         L/H

There is an access hole on the side of the motor which will allow you to adjust the tach stator with a screwdriver. You will need to back-drive the motor and be able to view the waveforms with a scope as shown in the datasheet. One scope probe will be on the motor winding U-V, and the other on the tach signal.

* Only if your motor has an additional encoder.

A common incremental encoder is tested with a separate cable, the TI-5022 (12 pin M23) or TI-5054 (17 pin MS).  Simply perform a Count Test to verify the encoder is working. The alignment of the encoder is not crucial since commutation is performed by the Hall effects.

The motor should be run from the Hall effects using the TI-3000JX “Generic Pulse>120Deg” selection.
