Parameter setting procedure (3)
When a linear motor is used, the linear encoder must be installed so
that the Z phase of the linear encoder matches the origin of the
activating phase. Otherwise, the specified motor characteristics
cannot be obtained. (For details of installation positions, refer to Part
III, “HANDLING, DESIGN, AND ASSEMBLY”".
Procedure (3) describes the method of adjusting the activating phase
origin (AMR offset adjustment) when it is difficult to install a linear
encoder at a specified position with a specified precision.
1762 - AMR offset
2139 -
Specifies an activating phase (AMR offset) for phase Z.
[Increment system] Degrees
[Valid data range] -45 to 45 (*)
* With Series 90B0/C(03) and subsequent editions, an extended
AMR offset setting range (-60 degrees to 60 degrees) can be
specified by setting the parameter below. So, if the AMR offset
value does not lie within the range -45 degrees to 45 degrees in
adjustment processing, set the bit below. (Usually, set the bit
below to 0.)
#7 #6 #5 #4 #3 #2 #1 #0
2683 - AMR60
2270 -
AMR60 (#0) Changes the AMR offset setting range.
0: -45 degrees to 45 degrees (standard setting range)
1: -60 degrees to 60 degrees (extended setting range)
The procedure for AMR offset adjustment is described below. The
procedure varies according to whether an incremental type linear
encoder or absolute type linear enable is used. Before starting an
adjustment, check the type of linear encoder used.
