ErrordetailsonCBV30
■
When error signals have been released using CN2#1 (RUN / STOP), the MDR
instantly starts up when RUN is input.
■
When the power supply voltage is dropped to 8.5 V or less, an operation when
the power is shutdown or an unexpected operation may occur.
■
When releasing an error, switch ON→OFF→ON signals on CN2#1, and ON→
OFF→ON / OFF→ON→OFF signals on CN2#2, at intervals of 100 ms or more.
Errors can be checked by PWR (Green), ERR (Red), and signals from CN2#3.
