Route control cables to minimize radiation to the cable:
• Route as far away as possible from the input power and motor cables (at least 20 cm (8 in)).
• Where control cables must cross power cables make sure they are at an angle as near 90º
as possible.
• Stay at least 20 cm (8 in) from the sides of the drive.
Use care in mixing signal types on the same cable:
• Do not mix analog and digital input signals on the same cable.
• Run relay-controlled signals as twisted pairs (especially if voltage > 48 V). Relay-controlled
signals using less than 48 V can be run in the same cables as digital input signals.
NOTE! Never mix 24 VDC and AC power signals in the same cable.
Analog Cables
Recommendations for analog signal runs:
• Use double shielded, twisted pair cable
• Use one individually shielded pair for each signal.
• Do not use a common return for different analog signals.
Digital Cables
Recommendations for digital signal runs:
• A double shielded cable is the best alternative, but single shielded twisted multi-pair cable
is also usable.
Control Panel Cable
If the control panel is connected to the drive with a cable, use only Category 5 Patch ethernet
cable.
