			(Normal: 0/Setting error: 1)
SD513	Manual pulse	Manual pulse	SD513 : The manual pulse generator axis setting error is stored in b0 to b2
		generator axis		(P1 to P3).
SD514	generator axis
		setting error		The smoothing magnification setting is stored in b3 to b5 (P1 to P3).

SD516	Error program	Error program No.	• When the servo program setting error flag (SM516) turns on, the erroneous
	No.	of servo program	servo program No. will be stored.
SD517	Error item	Error code of servo	• When the servo program setting error flag (SM516) turns on, the error code
	information	program	corresponding to the erroneous setting item will be stored.
