Example 3, reference point ö (fig. "Measuring the relative position

between primary and secondary part"):

g = 180.0 mm , k

= 38.0 mm , l

= 540.0 mm

P-0-0523 = 37.5 mm - g - l

- k

= 37.5 mm – 180.0 mm – 540.0 mm –

38.0 mm

P-0-0523 = – 720.5 mm

Carrying Out the Measuring Method (Commissioning)

• The determination of the commutation offset can only be used for

synchronous linear motors with absolute encoder (e.g. encoder with

EnDat interface).

• During the setting procedure below the drive must be in the A0013

Ready for power on status.

• The position of the primary part or the slide mustn't have changed

since the relative position of primary and secondary part was

measured.

• The correct value must have been entered in P-0-0018, Number of

pole pairs/pole pair distance.

1. Measure the reference between primary and secondary part.

2. Calculate the value for P-0-0523 with the appropriate formula for the

arrangement; enter the determined value in P-0-0523, Commutation

setting measured value.

3. Select the method by setting the respective bit in P-0-0522, Control

word for commutation setting.

4. Start the P-0-0524, C1200 Commutation offset setting command

in order to carry out the calculation of the commutation offset.

5. The controller enters the determined value in P-0-0521, Effective

commutation offset. If the commissioning mode was activated in

P-0-0522, Commutation setting control word the value from

P-0-0521 is accepted in P-0-0508, Commutation offset and

P-0-3008, Commutation offset, encoder memory, too.

6. The command then has to be reset again!
