11.SPINDLE SPEED FUNCTION B-63943EN-1/02
- 1322 -
The dual check safety function checks the positioning deviation with
the CNC CPU and servo DSP at all times. Only when the servo DSP
detects, during safety monitoring (with the safety monitor signal
SEV/SEP set to 1), that the positioning deviation in the stopped state
is exceeded, the servo alarm mode (SV0474) is issued.
1830 Axis-by-axis positional deviation limit at servo-off time
[Input type] Parameter input
[Data type] 2-word axis
[Unit of data] Detection unit
[Valid data range] 0 to 99999999
This parameter is used to set a positional deviation limit at servo-off
time, on an axis-by-axis basis.
If the value specified with this parameter is exceeded at servo-off time,
a servo alarm is issued to cause an immediate stop (same as an
emergency stop). Usually, set the same value as a positional deviation
at stop time.
1851 Backlash compensating value for each axis
[Input type] Parameter input
[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.

# 1 NRF With the first move command (G00) after switching the series spindle
to Cs contour control mode:
0: A reference position return operation is once performed then
positioning is performed.
1: A normal positioning operation is performed.
