Automatic Tool Changers (ATCs) require sub-millimeter precision. If the Z-axis home position is off by even
Parameter 1860 determines the sign (positive or negative) of the position feedback pulses relative to the commanded movement. fanuc parameter 1860 work
When a machine is equipped with absolute encoders, it does not need to be homed every time it is powered on because the CNC "remembers" the current position by reading the value stored in this parameter. Core Function and Mechanics Core Function and Mechanics : If set to
: If set to 1 , the CNC knows the axis has an absolute encoder. While Parameter 1820 sets the scale , Parameter
Using a non-contact spindle orientation sensor, they determine the spindle is stopping 0.05mm away from true zero radially. They calculate:
The Command Multiplier sets the ratio between the CNC's internal command units and the physical detection units. While Parameter 1820 sets the scale , Parameter 1860 sets the direction of that scale. Common Symptoms of an Incorrect Parameter 1860 Setting
