Honeywell VFD - Questions and Answers

Honeywell VFD - Questions and Answers
Question: What is an A/C choke? Answer: An A/C choke is the same as a 3% Line Reactor. They are built in to the line side of every Honeywell drive three horsepower and bigger. A/C chokes help prevent harmonic distortion from going back in to the supply line.
Question: Why do Honeywell drives have two ratings? Answer: Honeywell drives are rated for both constant torque (cranes, conveyors) and variable torque (fans, pumps, and compressors) applications. You can use a small drive when used on variable torque applications as long as the ambient temperature does not exceed 104 degrees Fahrenheit (122 degrees for constant torque applications) and the rated amps for the drive.
Question: What is the difference between the Industrial and Commercial RFI filters? Answer: The internal RFI filters are designed to fulfill European EMC emissions standards. The Industrial filter would be considered a "standard" filter. It meets EN50081-2. The Commercial filter is considered a "higher grade" filter. It meets EN50081-1 and EN50081-2.
Question: What are the seven prepackaged programs? Answer: Instead of trying to scroll through 300 parameters. Honeywell drives come standard with seven prepackaged programs. These programs are set up so you only have access to parameters you need to run your application. The programs are Basic, Standard, Local/Remote, P+I control, Multi-Purpose, Pump and Fan, and Multi-step.
Question: How can the Honeywell drive be controlled? Answer: The Honeywell drive can be controlled by a controller or with just a sensor. The drive will accept a 0/4-20ma or 0-10vdc signal. If the input is from a sensor the drive can be programmed to provide a P+I control loop. The VFD will also accept digital inputs for start/stop commands and multi-speed commands. Two relay outputs, one digital output and one analog output are also standard on every drive.
