1) Ground the FG terminal of the Motion controller and 24VDC power supply module to the control panel.
2) Measure against noise of the power supply cable
• Wire the power supply cable as short as possible using the twisted cable.
• Set a line filter (FR-BLF) near the exit/entrance of control panel and in secondary side of MCCB. (Approx. 4 turn)
3) Measure against noise of the encoder cable
• When the cables are extracted from the control panel, ground the cables at a position 5 to 10cm (1.97 to 3.94inch) away from the exit/entrance
of the control panel with the cable clamp, etc.
• Refer to the Section 2.5.5 and Appendix 1.2 for encoder cable.
Use shielded twisted pair cable.
4) Measure against noise of the manual pulse generator/external signal input cable
• When the cables are extracted from the control panel, ground the cables at a position 5 to 10cm (1.97 to 3.94inch) away from the exit/entrance
of the control panel with the cable clamp, etc.
• Refer to the Section 2.5.6 for manual pulse generator.
Use shielded twisted pair cable.
• Refer to the Section 2.5.4 for external signal input.
Use shielded twisted pair cable between the external signal and COM signal.
• When the cables are connected to internal I/F connector of Q173DSCPU/Q172DSCPU and extracted from the control panel, ground the
cables at a position 20 to 30cm (1.97 to 3.94inch) away from the module with the cable clamp, etc. Use a shielded cable.
• Refer to the Section 2.5.1and Appendix 1.5 for internal I/F connector cable.
5) Measure against noise of the internal I/F cable
• When the cables are extracted from the control panel, ground the cables at a position 20 to 30cm (1.97 to 3.94inch) away from the module
with the cable clamp, etc. Use a shielded cable.
(1) Refer to Section 2 for the following cables.
• Ethernet cable
• USB cable
• SSCNET
cable
• Battery cable
• Forced stop input cable
