Control Cables

General Recommendations

Use shielded cables, temperature rated at 60 °C (140 °F) or above:
• Control cables must be multi-core cables with a braided copper wire screen.
Example: JAMAK by Draka NK Cables
• The screen must be twisted together into a bundle not longer than five times its
width and connected to terminal X1-1 (for digital and analog I/O cables) or to
either X1-28 or X1-32 (for RS485 cables).
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 90° 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 115/230 VAC 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.
Double Shielded
Single Shielded
