Section 9 Multi-Function Timer Pulse Unit 2 (MTU2)
Operation when Error Occurs during Phase Counting Mode Operation, and Operation is
Restarted in Phase Counting Mode: Figure 9.143 shows an explanatory diagram of the case
where an error occurs in phase counting mode and operation is restarted in phase counting mode
after re-setting.
