8. Determine the angular commutation offset of motor 2
For an incremental measuring system:
as for Chapter 4.10.2, Point 5. (determining the angular commuta-
tion offset)
For an absolute measuring system:
Power–down the drive (POWER ON–RESET)
Power–up the drive with the pulse or controller enable signals
switched–out
Set P1017.0 to 1
Switch–in the pulse and enable signals
––> The angular offset is automatically entered into P1016
––> Fault 799
(Save to FEPROM and HW–RESET required)
is displayed
Save to FEPROM and carry–out a HW–RESET
9. Traverse the axis and check that it is functioning correctly
10.Note the angular commutation offset of motor 2
– P1016 (motor 2) = _ _ _ _ _ _ _ _ degrees electrical
11.Deviation between Point 4. (motor 1) and Point 10. (motor 2)
if 10 degrees––> OK
If > 10 degrees
––> Check and correct the mechanical arrangement
(refer to Chapter 4.10.4 and 4.10.7)
or
––> Carry–out a check by making the appropriate measurements
(refer to Chapter 4.10.8)
12.Delete the drive configuration
Operator action: ”Options – Service – Delete drive configuration”
13.Power–down and wait until the DC link has been discharged
14.Connect the 2 linear motors in parallel again
Connect both of the motors back to the power module.
15.Power–up with the pulse and controller enable signals switched out
16.Commission the linear motors connected in parallel
– Work completely through Chapter 4.10.2
– In the ”motor selection” dialog box, select the motor connected in
parallel (2 1FNx ...)
or
enter the data of the unlisted motor connected in parallel (refer
under the index entry ”unlisted motor – parameters for SLM”)
