3-9-1 Preparing the encoder cable and the I/ O cable
Follow these instructions for the preparation of the encoder cable and the I/O cable.
(1) Use twisted pair cables for I/O signals, and for encoder signals cables. When a host controls several
drivers, prepare I/O signal cables for each driver individually.
(2) Make the length of signal cables as short as possible.
(a) I/O signal cable: 3m or less
(b) Encoder signal cable (user’s responsibility): 20m or less, providing that the condition of wire
conductivity is less than 0.04 ohm/m. Cable for 3m/5m/10m are available for option.
(3) Separate power cables (power source cables and motor cables) and I/O signal cables in 30cm or
more. Do not encase both cables in one pipe or duct, nor bundle them.
(4) Do not open the end of analog signal cables as speed signal cables.
