After turning OFF the M code ON signal, start the
system. (Refer to Section 12.7.3)
Check the sequence program which turns ON/OFF the
PLC READY signal (Y0), and turn ON the PLC READY
signal. Then start the system.
Check the QD75 READY ON signal, and then start the
system. (Refer to Section 3.3.2)
Normalize the positioning start No.
(Refer to Section 12.7.7)
Correct the positioning data.
(Refer to Section 9.2.10, 9.2.11)
Set 1 to 65535 for number of repetitions of the "LOOP".
(Refer to Section 9.2.22)
• Set the ABS setting direction in the unit of degree
within the setting range.
• Set "0" when the software stroke limits are valid.
(Refer to Section 9.1.5)
Invalidate the software stroke limit.
(To invalidate, set the software stroke limit upper limit
value to the software stroke limit lower limit value.)
(Refer to Section 9.1.5)
Correct the positioning data "M code ON signal output
timing" to 0 to 2.
Correct the positioning data "Interpolation speed
designation method" to 0 to 2.
Correct the number of pitch set in the positioning data
"M code" of the linear interpolation axis to 0 to 999.
