4. DESCRIPTION OF PARAMETERS
65
1851 Backlash compensating value for each axis
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 9999 to +9999
Set the backlash compensating value for each axis.
When the machine moves in a direction opposite to the reference position
return direction after the power is turned on, the first backlash
compensation is performed.
1855 Current limit override value for each axis
[Data type] Byte axis
[Valid data range] 0 to 255
This parameter specifies a current limit override value for each axis.
Override value = Setting*100/255(%).
NOTE
When 0 is specified, torque control based on this parameter
is not exercised. (A DI signal and PMCset torque value
become valid.)
1872 Servo positional deviation check value
[Data type] 2-word axis
[Valid data range] 0 to 99999999
This parameter specifies a servo positional deviation check value. When
this value is exceeded, signals SVER1 to SVER8 are turned on.
1880 Abnormal load detection alarm timer
[Data type] Word axis
[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 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 8
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
0 is set for an axis, movement along that axis is stopped whenever an
abnormal load is detected for any axis.
