4-1 High-speed Counter Specifications
<Special notes>
Wiring must use the shield line. Ground shielded wires.
Please connect the shield appropriately according to the specification of the pulse encoder and the connection with the
controller.
The signal from the encoder might malfunction by interfering with A phase and B phase when the wiring between the
encoder and the inverter is long. In this case, please execute measures such as; wiring shorter cable, cable of smaller
electrostatic capacity, etc.
