Always check the specifications of the motor driver before actually connecting it. For open-collector output, use a maximum of 3 m of wiring between the CP1H CPU Unit and the motor driver. No pulses are output while the pulse output transistor is OFF. For a direction output, OFF indicates that CCW output is in progress. Do not use the same power supply for both pulse output 24-VDC/5-VDC power and other I/O power.

Be careful to ensure that the Position Control Unit output current does not damage the input circuit at the motor driver and yet is sufficient to turn it ON. Take into account the power derating for the 1.6-kΩ resistance. 129

(2) For any inputs that are not to be used, set them to not be used by clearing the selection of the Use checkbox. If an input that is set to be used is not actually used, the data for that input may be unstable. If that occurs, the instability can be removed by short- 131

If the range is set for 1 to 5 V and 4 to 20 ma, however, the Open-circuit Detection Flag will turn ON when the plus and minus terminals are short-circuited. Terminal Block Wiring When wiring the analog I/O terminal block, either use ferrules or solid wires. 2-conductor shielded twisted-pair cable Release button Ferrules Wire the terminal block while it is mounted to the CPU Unit and do not remove it from the CPU Unit after completing wiring. To make the connection, insert the ferrule or solid wire into the round hole in the terminal block it locks inside. To disconnect the wiring, press the release button in with a small flatblade screwdriver and pull the line out while the lock is released. The screwdriver shown below is recommended for disconnecting wiring.

10 CP-series Expansion I/O Unit Wiring Section 3-6 I/O Wiring Precautions To enable using the analog I/O under optimal conditions, be careful of the following points for noise reduction. Use 2-conductor shielded twisted-pair cable for the I/O wiring, and do not connect the shield. Wire I/O lines apart from power lines (AC power supply lines, three-phase power lines, etc.), and do not place them in the same duct. If noise is received from power supply lines (e.g., when sharing a power supply with electric welding machines or electric charging devices, or when near a high-frequency source), insert a noise filter in the power supply input section. 3-6 CP-series Expansion I/O Unit Wiring CP-series Expansion I/O Units 40-point I/O Units 32-point Output Units 20-point I/O Units 16-point Output Units 8-point Input Units 8-point Output Units Model Inputs Outputs CP1W-40EDR CPM1A-40EDR CP1W-40EDT CPM1A-40EDT CP1W-40EDT1 CPM1A-40EDT VDC inputs 16 relay outputs 16 transistor outputs (sinking) 16 transistor outputs (sourcing) CP1W-32ER None 32 relay outputs CP1W-32ET 32 transistor outputs (sinking) CP1W-32ET1 32 transistor outputs (sourcing) CP1W-20EDT1 CPM1A-20EDR1 CP1W-20EDT CPM1A-20EDT CP1W-20EDT1 CPM1A-20EDT1 CP1W-16ER CPM1A-16ER CP1W-16ET CP1W-16ET1 CP1W-8ED CPM1A-8ED CP1W-8ER CPM1A-8ER CP1W-8ET CPM1A-8ET CP1W-8ET1 CPM1A-8ET VDC inputs None 8 24-VDC inputs None 8 relay outputs 8 transistor outputs (sinking) 8 transistor outputs (sourcing) 16 relay outputs 16 transistor outputs (sinking) 16 transistor outputs (sourcing) None 8 relay outputs 8 transistor outputs (sinking) 8 transistor outputs (sourcing) For details on wiring Expansion Units, such as Analog I/O Units, Temperature Sensor Units, CompoBus I/O ink Units, and DeviceNet I/O ink Units, refer to SECTION 7 Using CP-series Expansion Units and Expansion I/O Units. 133
