4. DESCRIPTION OF PARAMETERS
B–64160EN/01
68
If the value specified with this parameter is exceeded at servo–off time, a
servo alarm (No.410) is issued to cause an immediate stop (same as an
emergency stop). Usually, set the same value as a positional deviation at
stop time (parameter No.1829).
NOTE
When this parameter is set to 0, no positional deviation limit
check is made at servo–off time.
1836 Servo error amount where reference position return is possible
[Data type] Byte axis
[Unit of data] Detection unit
[Valid data range] 0 to 127
This parameter sets a servo error used to enable reference position return
in manual reference position return.
In general, set this parameter to 0. (When 0 is set, 128 is assumed as the
default.)
NOTE
When bit 0 (PLC01) of parameter No.2000 is set to 1, a value
ten times greater than the value set in this parameter is used
to make the check.
Example
When the value 10 is set in this parameter, and bit 0 (PLC01)
of parameter No.2000 is set to 1, reference
1850 Grid shift and reference position shift for each axis
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
[Data type] 2–word axis
[Unit of data] Detection unit
[Valid data range] 0 to 99999999 (for reference position shift)
Reference counter size or less (for grid shift)
To shift the reference position, the grid can be shifted by the amount set in
this parameter. Up to the maximum value counted by the reference
counter can be specified as the grid shift.
In case of parameter SFD (No.1002#2) is 0: Grid shift
In case of parameter SFD (No.1002#2) is 1: Reference point shift
