Appendix4 SPECIAL REGISTER LIST
SD1860
Axis 2 current
feed value
Current feed value
This register stores the current position value when the
position where OPR control is completed is set as a
base point.
"0" is stored at power-on or reset of the CPU module.
An OP address is stored at the completion of machine
OPR control.
This register is cleared to "0" when speed control in
speed/position switching control is started.
•When the current feed value is changed, the value
after current value change is stored.
•The current position read from a servo amplifier is
stored at the completion of absolute position
restoration.
*1*2
*1 Range: -2147483648 to 2147483647 pulses
*2 Since the internal update cycle of the storage value
is 1ms, the information of the current feed value may
be older than the actual command position by 1ms
at maximum depending on the refresh timing at END
processing.

SD1862
Axis 2 current
speed
Current speed
This register stores the current speed. (Fractions are
not stored. If the current speed is slower than 1 pulse/s,
"0" may be displayed.)
*1*2
*1 Range: 0 to 200000 pulses
*2 Since the internal update cycle of the storage value
is 1ms, the information of the current speed value
may be older than the actual command position by
1ms at maximum depending on the refresh timing at
END processing.

SD1864
Axis 2 axis
operation status
Axis operation
status
This register stores the axis operating status.
•-1: Error occurring
•0: Standing by
•1: Stopped
•2: In JOG operation
•3: In OPR
•4: In position control
•5: In speed-position control (speed) (speed
control in speed/position switching control)
•6: In speed-position control (position) (position
control in speed/position switching control)
•7: Decelerating (axis stop ON)
•8: Decelerating (JOG start OFF)
•9: In high-speed OPR
•10: In speed control
•11: Analyzing
SD1865 Axis 2 error code Error code
• This register stores the error code of the present axis
error.
• If another error occurs while an axis error occurs, the
latest error code is not stored.
• This register is cleared to "0" by turning on SM1870.
SD1866
Axis 2 warning
code
Warning code
• This register stores the warning code of the present
axis warning.
• If another axis warning occurs, the latest warning
code is written to this register.
• This register is cleared to "0" by turning on SM1870.
