6-1. Connection between Converter and ABSOCODER Sensor
The cable connector is connected to the sensor connector
of the converter. The ABSOCODER sensor is equipped with
a 2-meter interconnecting sensor cable. If a longer length is
required, dedicated extension sensor cable must be used.
-Wiring Precautions
(1) The sensor cable should be clamped as shown
in the right figure to prevent excessive tension from
being applied to the cable connectors.
(2) The sensor cable should be located at least 300mm
away from power lines and other lines which generate
a high level of electrical noise.
(3) If the cable is moved under the state of bending
like a horseshoe, a robotic cable should be used.
The bend radius should never be less than 75 mm.
6-2. Power Supply Connection
The power supply should be connected as described below:
(1) Power Supply
- The rush current is 10A (rush time of 20ms), so
select the power supply after due consideration.
Choose the capacity of the power supply over
double of power consumption of converter.
- Use a power supply of 24VDC, and 8A or less.
- The input power supply should be isolated from
the commercial power supply.
- The power cable should be as thick as possible
to minimize voltage drops.
- Twist the power cable for preventing noises.
- Use the M3 size crimp lug terminals with
insulating sleeves in order to prevent short
circuit caused by loose screws. (Torque: 0.6N-m).
- Connect the power supply via a 4A (max.) over-current protection circuit.
(2) Ground
- The unit should be securely grounded (ground resistance of 100ohm or less) to prevent electrical shocks.
- The power cable should be as thick as possible.
