5 MOTION DEDICATED PLC INSTRUCTION
[Controls]
(1) This instruction is dedicated instruction toward the Motion CPU in the Multiple
CPU system. Errors occurs when it was executed toward the CPU except the
Motion CPU.
(2) The torque limit value of the axis specified with (S1) is changed to the value of
(S2) regardless of the state of during operating or stopping at the real mode.
(3) S(P).SFCS/S(P).SVST/S(P).CHGA/S(P).CHGV/S(P).CHGT/S(P).DDRD/
S(P).DDWR cannot be executed simultaneously toward the CPU executing
S(P).CHGT instruction.
When the Motion dedicated PLC instruction is started continuously, It is necessary
to take an inter-lock by the to self CPU high speed interrupt accept flag from
CPUn.

Torque limit value change processing
[Setting range]
(1) Setting of the axis to execute the torque limit value change.
The axis to execute the torque limit change set as (S1) sets J + axis No. in a
character sequence " ".
(S1) usable range
Q173CPU(N) 1 to 32
Q172CPU(N) 1 to 8
The number of axes which can set are only 1 axis.
The axis No. set in the system setting (Refer to Section 1.5) is used as the axis
No. to start.
(2) Setting of the torque limit value to change.
(S2) usable range
1 to 500
