Rotation Instructions - Mitsubishi MELSEC QCPU Programming Manual

2 INSTRUCTION TABLES
2) 2:The number of steps may vary depending on the device and type of CPU module being
used.
Component
High Performance model QCPU
Process CPU
Basic model QCPU
QnCPU
Note 1:With High Performance module QCPU, (1) requires more number of steps, while it can
process the steps faster, as compared with (2).
Note 2:The number of steps may increase due to the conditions described in Section 3.8.
3) 3 : The subset is effective only with QCPU.
