5. External Wiring 5.1 Wiring Precautions 1) Different terminals have been prepared for connection depending on the voltage of the input signal. Connecting a terminal of incorrect voltage may result in malfunction or mechanical failure. 2) For 1-phase input, always perform pulse input wiring on the Phase A side. 3) For the QD62 (E/D), count will be performed if pulse status noise is input and a miscount will result.
