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 Unexpected disturbance torque detection alarm timer
[Data type] Word
[Unit of data] ms
[Valid data range] 0 to 32767 (200 msec is assumed when 0 is set)
This parameter sets the time from the detection of an unexpected
disturbance torque 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 unexpected disturbance torque is detected
[Data type] Byte axis
[Valid data range] 0 to 4
This parameter sets the group number of each axis, used when an
unexpected disturbance torque is detected.
If an unexpected disturbance torque is detected for an axis, only the
movement along the axes of the group containing the axis with the
unexpected disturbance torque is stopped. If 0 is set for an axis,
movement along that axis is stopped whenever an unexpected
disturbance torque is detected for any axis.
[Example]
Assume that the following settings have been made. If an
unexpected disturbance torque is detected for the first axis,
movement along the first, third, and fourth axes is stopped. If an
unexpected disturbance torque is detected for the second axis,
movement along the second and fourth axes is stopped.

NOTE
This parameter is enabled when the ANA
parameter (bit 5 of parameter No.1804) is 1.
