: Always combine,
: Combination possible,
1 The operation pattern is one of the "positioning data" setting items.
2 The near pass function is featured as standard and is valid only for setting continuous path control for position control.
3 Invalid during creep speed.
4 Invalid during continuous path control.
5 Inching operation does not perform acceleration/deceleration processing.
6 Valid for the reference axis only.
7 Valid for only the case where a deceleration start is made during position control.
8 Disabled for a start of positioning start No. 9003.
9 Valid for " Md.22 Feedrate " and "
10 Valid for a start of positioning start No.9003, but invalid for a start of positioning data (No. 1 to 600).
With positioning control using the QD75MH, the main functions and sub functions can
be combined and used as necessary. A list of the main function and sub function
combinations is given below.
Sub functions
