NSD ABSOCODER NCW-3DNECMP Specifications & Instruction Manual page 71

● Circuit resistance check
[Measurement method]
Measure resistance at Point A or B using a circuit tester or other appropriate device.
If the connector is off, identify the line by the wiring color.
[Check details]
Refer to the previous page for the connector pin number.
Check position
Between brown and red
Between orange and yellow
Between green and blue
Between violet and gray
*1: If checks are done at Point B, the measurement value is [Standard coil resistance + extension sensor
cable resistance (cable length (m) x 0.2 (Ω))].
The resistance value of the NSD special cable is 0.2Ω/m (loop resistance).
Consider resistance variations due to temperature, which, relative to the standard temperature (25
increases 0.4% when the temperature rises 1
● Insulation check
[Measurement method]
Measure using a 500 VDC insulation tester.

NOTES
1. Make sure to disconnect the ABSOCODER sensor from NCW-3DNEC before carrying out insulation checks.
2. If there is a risk that energization may cause damages to the electronic circuits in and around the machine,
remove the ABSOCODER sensor from the machine.
3. After completing the checks, short-circuit between the pins to discharge remaining voltage before
connecting the ABSOCODER sensor to NCW-3DNEC.
