4 In subsequent reference position return, the machine stops at the
reference position.
- Adjustment procedure using the reference position adjustment signal
1 Set the parameters below. After setting these parameters, turn the
power off then back on to make the settings effective.
Bit 4 (SFD) of parameter No. 1008 = 1
Grid shift amount (parameter No. 1844) = 0
Reference position shift amount (parameter No. 1850) = 0
2 Perform reference position return. The machine stops at the first
grid point after leaving the deceleration dog. A grid shift amount is
set automatically, and is indicated in diagnosis No. 3008.
3 Set reference position adjustment signal RASTn to 1, then perform
manual movement from the stop position to the reference position.
Next, set the reference position adjustment signal to 0 at that
position. Then, the manually moved distance is automatically set
in parameter No. 1850 (reference position shift amount). Then,
turn off the power before continuing the operation. This completes
reference position adjustment.
4 In subsequent reference position returns, the machine stops at the
reference position.
