10. Multifunction Timer Pulse Unit (MTU)
(16) Operation when Error Occurs during Phase Counting Mode Operation, and Operation
is Restarted in Phase Counting Mode: Figure 10.75 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.
