Mitsubishi Electronics Q172HCPU, Q173HCPU 3.1 Internal Relays, (1) Internal relay list, 3 POSITIONING DEDICATED SIGNALS

3 POSITIONING DEDICATED SIGNALS

The positioning dedicated devices are shown below.

It indicates the device refresh cycle of the Motion CPU for status signal with the positioning control, and the device fetch cycle of the Motion CPU for command signal with the positioning control.

The operation cycle of the Motion CPU is shown below.
