Not applicable to absolute type encoders.
When using encoders from other manufacturers, check if the encoders are within the
specification range of CEU5 before use (Refer to the previous page and this page).
Performance test is given to SMC Monosashi-kun (Scale reading cylinders) and CEU5
using a 23 meter long exclusive extension cable. Wiring length depends on the specifications
of the encoder and cable given by each manufacturer and it should be checked before use.
CEU5 has a power supply for encoder (12VDC, 60 mA). If an encoder requires a power
other than 12VDC or large current consumption, use a separate power supply.
