B–63380EN/02
66
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, #4 of parameter No.1800, is set to 1. When RBK is set to 0, the normal
backlash is performed.
1870 Number of the program for storing servo trace data
[Data type] Word axis
[Valid data range] 0 to 9999
Set the number of the program for storing servo trace data.
1874 Number of the conversion coefficient for inductosyn position detection
1875 Denominator of the conversion coefficient for inductosyn position detection
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
[Data type] Word axis
[Valid data range] 1 to 32767
Set a conversion coefficient for inductosyn position detection for each
axis. The value set is determined as follows:
=
Number of position feedback pulses per motor revolution
1,000,000
No. 1874
No. 1875
1876 One–pitch interval of the inductosyn
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 1 to 32767
Set a one–pitch interval of the inductosyn for each axis.
