Appendix 8.1.6; Precautions When Using A Melsec-A Series Module - Mitsubishi Electric Q26UD(E)HCPU User Manual

Appendix 8.1.6

This section describes precautions when a MELSEC-A series module is used by connecting the QA1S5B,
QA1S6B, QA1S6ADP+A1S5B/A1S6B, QA6B, or QA6ADP+A5B/A6B extension base unit to the system.
(1) Cable
(a) Grounding the shield section of shielded cable
For the grounding method, refer to, refer to Page 655, Appendix 8.1.3 (1).
(b) Positioning modules
Precautions for configuring the machinery compliant with the EMC Directives using the A1SD75P-S3
(abbreviated as A1SD75 hereafter), AD75P-S3 (abbreviated as AD75 hereafter) are described below.
1) When wiring cable of a 2m or less
• Ground the shield of the external device connection cable with a cable clamp. (Ground the shield at the
closest location to the A1SD75/AD75 external wiring connector.)
• Wire external device connection cables to drive modules and external devices by the shortest distance.
• Install the drive unit in the same panel.
2) When wiring with cable that exceeds 2m, but is 10m or less
• Ground the shield of the external device connection cable with a cable clamp. (Ground the shield at the
closest location to the A1SD75/AD75 external wiring connector.)
• Wire external device connection cables to drive modules and external devices by the shortest distance.
• Install a ferrite core.
