■Command generation axis start accept flag (System area)
When the servo program start is executed by specifying "Jn" as axis No., the complete status of start accept flag is stored in
the address of the start accept flag in the CPU shared memory for target CPU.
CPU shared memory address( )
is decimal address
20EH(526)
20FH(527)
210H(528)
211H(529)
■Control change for the command generation axis
The following control change can be performed for the command generation axis.
• Current value change
• When CHGA instruction of servo program (Kn) is used
CHGA instruction of servo program assigned to the range used by the command generation axis with the command generation axis program allocation
setting is used.
• When the current value changed is executed by Motion dedicated PLC instruction
M(P).CHGAS/D(P).CHGAS instruction is used.
Ex.
The current value is changed to 1000 for the command generation axis 3 of CPU No.2.
• Speed change
• When the speed changed is executed by Motion SFC program
CHGVS instruction is used.
Ex.
The speed is changed to 100000 for the command generation axis 4.
CHGVS(K4,K100000)
• When the speed changed is executed by Motion dedicated PLC instruction
M(P).CHGVS/D(P).CHGVS instruction is used.
Ex.
The speed is changed to 300000 for the command generation axis 5 of CPU No.2.
■Simultaneous start instruction of command generation axis program
In simultaneous start instruction (START), the simultaneous start is not possible with real axis program and command
generation axis program mixed. If the mixed programs are started with the programs mixed, the minor error (error code:
1A4FH) will occur.

Description
The command generation axis start accept flag for 64 axes are stored corresponding to each bit. Bits are actually
set as the following.
• R64MTCPU: J1 to J64
• R32MTCPU: J1 to J32
• R16MTCPU: J1 to J16
OFF: Start accept enable
ON: Start accept disable
