4. DESCRIPTION OF PARAMETERS
99
=
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.
SUPPLEMENTAL REMARK
To use an absolute–position detector using Inductosyn, set
the following digital servo parameters as well:
Bit 4 (INDx) of parameter No. 2015
The absolute–position detect function by
Inductosyn is:
0 : Disabled.
1 : Enabled.
Parameter No. 2141 Inductosyn data acquisition time
Set a time requirement for acquiring the
Inductosyn data. If the setting is 0, 20 ms is
assumed. (For the setting, contact the scale
manufacturer.)
1880 Abnormal load detection alarm timer
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 32767 (200 mse is assumed when 0 is set)
This parameter sets the time from the detection of an abnormal load until a
servo alarm is issued. The specified value is rounded up to the nearest
integral multiple of 8 msec.
[Example] When 30 is specified, the value is rounded up to 32 (msec).
1881 Group number when an abnormal load is detected
[Data type] Byte axis
[Valid data range] 0 to 4
This parameter sets the group number of each axis, used when an
abnormal load is detected.
If an abnormal load is detected for an axis, only the movement along the
axes of the group containing the axis with the abnormal load is stopped. If
