Chapter 4 Installing HA-655 driver<br />
4-4-3Instructions for cabling<br />
In addition to the noise suppression mentioned previously, one must also follow these instructions:<br />
(1) Use twisted pair cables for I/O signals, and for encoder signals cables. When a host controls<br />
several drivers, prepare I/O signal cables for each driver individually.<br />
(2) Make the length of signal cables as short as possible.<br />
(a) I/O signal cable: 3m or less<br />
(b) Encoder signal cable (user’s responsibility): 20m or less, providing that the condition of wire<br />
conductivity is less than 0.04 ohm/m.<br />
Optional cables of 3m/5m/10m long are available.<br />
(3) Install surge protector devices to magnetic relays coils, magnetic switches, and solenoids.<br />
(4) Separate power cables (power source cables and motor cables) and I/O signal cables by more<br />
than 30cm. Do not encase both cables in one pipe or duct, and do not bundle them.<br />
(5) Do not open the end of analog signal cables such as <strong>speed</strong> signal cables.<br />
(6)As the HA-655 driver is designed for industrial use, it provides no specific radio interference<br />
provisions. Accordingly, line filters should be inserted for the power supply cables in the event that<br />
the driver:<br />
- is used in the vicinity of private residences.<br />
-causes apparent radio interference.<br />
