Sélection & Notes de remplacement

1. Critical distinction during replacement: DT1 = PNP sourcing; DT = NPN sinking. Reverse polarity connection may damage output circuits directly.
2. No onboard serial port. Modbus communication with HMI or inverters requires optional CP1W-CIF01/11 communication boards.
3. Logiciel de programmation: Programmeur CX (CX-P), supports Ladder Diagram, Schéma des blocs fonctionnels, Texte structuré.
4. Replacement options for phase-out: CP1E-N40DT1-D or NX1P compact NX series.

Troubleshooting for Common Faults

No pulse output: Verify output polarity matches servo/stepper drive signal type; check pulse output bits, frequency and axis parameters.

Échec de communication: Confirm communication board model, port number, baud rate and slave address; fit 120Ω terminating resistors at both ends of RS485 bus.

RUN indicator off after power-up: Check fatal program errors, PLC mode switch and battery fault.
