Technical Data
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
Recommendation 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. The maximum length that is tested to meet EMC specifications is 3 m
(9.8 ft). Longer cables are susceptible to electromagnetic noise and must be user-
tested to verify that EMC requirements are met. Where long runs are required
(especially for runs longer than about 12 m (40 ft)), use a RS232/RS485 converter at
each end and run RS485 cable.
