B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 117 -
NOTE
1 Jog feed is regarded as cutting feed.
2 The backlash compensation depending on a rapid
traverse and a cutting feed is not performed until
the first reference position return is completed after
the power is turned on. The normal backlash
compensation is performed according to the value
specified in parameter No.1851 irrespective of a
rapid traverse and a cutting feed.
3 The backlash compensation depending on a rapid
traverse and a cutting feed is performed only when
RBK, bit 4 of parameter No.1800, is set to 1. When
RBK is set to 0, the normal backlash is performed.
1867
Threshold for scale data conversion (common to all axes)
[Data type] 2-word
[Unit of data]
Increment system IS-A IS-B IS-C Unit
Rotation axis 0.01 0.001 0.0001 deg
[Valid data range] 0 to 99999999
If scale data is greater than the setting of this parameter, data for one
turn is subtracted from the scale data so that continuous scale data is
obtained within the movable range. The threshold to be set must be
the scale data of a position outside the movable range (an angle from a
discontinuous point). This parameter is common to all axes. If a
non-zero value is set in parameter No. 1868 for an axis, this parameter
is invalid for that axis.
NOTE
1 When this parameter has been set, the power must
be turned off before operation is continued.
2 This parameter is valid only for axes for which bit 3
(SCR) of parameter No. 1817 is set to 1.
3 When you have changed this parameter, establish
the reference position again.
