EMC wiring Guidelines
Cable routing
It is recommended that the power and signal cables for the ACS Drive be routed as
far apart as possible to minimize system noise.
NOTE!
The standard cables from Tolomatic are not flex rated and have a minimum
bend radius of 3.75 inches. Any repeated flexing or excessive bending can result in
broken conductors and intermittent faults.
Shielding and grounding
When cabling the system, shielded cables are recommended. The standard cables
provided by Tolomatic have an overall shield with drain wires. The metal angle
bracket on the drive/controller is also a case ground and should be tied to earth
ground. To minimize EMI and ensure system reliability, all shield drain wires from all
cables should be tied to a common earth ground.
Proper and Safe Use of Product
Protection circuits and external fuses
A fuse should be added to the input power line to protect the drive/controller and
power supply from any potential over current conditions that may occur. (See
Section 6: Specifications & Wiring, page 6-6i)
Fail Safe Emergency Stop Recommendations
A means for a fail safe e-stop is highly recommended to ensure equipment and
personal safety. The e-stop should provide a means to remove main power from the
actuator to cease and prevent any unwanted motion.
device damage Prevention
To prevent permanent damage to the device, proper care should be taken not to
exceed published voltage, current, temperature, and load ratings. In addition, proper
wiring should be verified and safety measures checked before applying power.
Personal Safety
During normal operation the motor can become hot. It is highly recommended to
display proper safety notices and implement proper safety measures to prevent
contact with hot surfaces.
