4. Replacement options for phase-out: CP1E-N40DT1-D or NX1P compact NX series.

Troubleshooting for Common Faults

Sin salida de pulso: Verify output polarity matches servo/stepper drive signal type; check pulse output bits, frequency and axis parameters.

Fallo de comunicación: 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.
