Control using CHGA instruction
(1) Executing the CHGA instruction changes the current value in the following
procedure.
(a) The start accept flag (M2001 to M2032) corresponding to the specified axis
is turned on.
(Note): For the command generation axis, [St.345] Command generation
axis start accept flag (M9810+20n) corresponding to the specified
axis is turned on.
(b) The current value of the specified axis is changed to the specified address.
(c) Start accept flag is turned off at completion of the current value change.
(2) The current value of the specified axis is changed in the SV13/SV22 real mode.
The address which made the current value change by CHGA instruction is valid
on the power supply turning on.
(3) The current value of the specified virtual servo motor shaft is changed in the
SV22 virtual mode.
(4) The current value of the specified command generation axis is changed in the
SV22 advanced synchronous control.
