5. Switch off and wait until DC link has discharged
6. Connect motor 2 to the power section instead of motor 1
Warning:
In a back-to-back arrangement (see section 6.10.7), remember to swap over
phase U and V.
7. Switch on motor with pulse and controller enabling signals inhibited
8. Determine the commutation angle offset of motor 2
With an incremental measuring system:
(see subsection 6.10.2, point 7.: “Determining the commutation angle
offset”)
With an absolute measuring system:
Switch off drive (NCK-Reset)
(see subsection 6.10.2, point 7.: “Determining the commutation angle
offset”)
9. Move axis and check correct function
(see subsection 6.10.2, step 9.)
10. Note the commutation angle offset of motor 2
MD 1016 (motor 2) = _ _ _ _ _ _ _ _ degrees electrical
11. Difference between step 4. (motor 1) and step 10. (motor 2)
if v 10 degrees ––> OK
if u 10 degrees ––> Check mechanical structure and correct
(see subsections 6.10.4 and 6.10.7)
Delete motor data for individual motor ––> Deleted boot file
12. Switch off and wait until DC link has discharged
13. Set up parallel connection of the 2 linear motors again
Connect both motors to the power section again.
14. Switch on motors with pulse and controller enabling signals inhibited
15. Start-up of paralleled linear motors
Carry out the complete start-up procedure described in
subsection 6.10.2
Select the paralleled motor from the “Motor selection” dialog.
(2x1FN. ...) or:
Enter the data for the paralleled non-Siemens motor (as described under
the heading of “Non-Siemens motors – parameters for SLM”).
16. Compare the commutation angle offset between motor 1 and 2
Check connection between motor cable and power section, correct if
necessary and determine the commutation angle offset.
With an incremental or absolute measuring system:
As described in subsection 6.10.2, point 7.: “Determining the commuta-
tion angle offset”.
