The conduit box option may be used with a cable clamp for a grounding point for the cable shield. Fast positive changes in input voltage or imbalanced input voltages can cause uncommanded positive speed changes; 2. Wire gauge requirements and recommendations are based on 75 degree C. Check the motor and drive output terminal wiring for a shorted condition. Motor GroundThe motor ground must be connected to one of the ground terminals on the drive. The PowerFlex safe off option is just one safety control system.
Enter Advance one step in programming menu. C-5Reading 03 Logic Status Data. J Terminal Description Important: A quadrature encoder provides rotor speed and direction. This attention to detail can add years to the life of your PowerFlex 40 drive, and we stand behind these repairs with our all-inclusive warranty that covers the entire drive for the warranty period, not just the parts that were replaced or work that was done. See the chart below for the override priority.
Refer to Start and Speed Reference Control on page 1-23 for details about how other drive settings can override the setting of this parameter. An additional foil shield can greatly improve noise containment. Application specific thermal considerations may require a larger enclosure. Bit 3 Drive Homed indicates whether the drive has been homed since power-up. Used when motor cannot be uncoupled from the load. This indicates that the drive is ready for operation.
Do not use cable with an insulation thickness less than 15 mils 0. Refer to Appendix E for details. For complete troubleshooting information, refer to the PowerFlex 40 User Manual. Cancel a change to a parameter value and exit Program Mode. When enabled, this parameter will change the frequency command in real time. Above 1000 m 3300 ft derate 3% for every 305 m 1000 ft. For additional flexibility one of the other settings should be used.
A054 09 Opto Common For opto-coupled outputs. None Set switch to match wiring scheme. Requires a Communication Adapter Cover Ordered Separately. B, install one of the devices listed under the heading Corrective Action on the line side of the drive. For additional information refer to Appendix F.
I will be happy to walk anyone through that, but right now I am trying to figure out the Powerflex Steplogic programming so I can automate the cross feed and down feed. Throughout this manual, when necessary we use notes to make you aware of safety considerations. Advanced Display Group View Only Consists of advanced drive operating conditions. Common Symptoms and Corrective Actions. C-7Reading 03 and Writing 06 Drive Parameters. General Notes If the plastic top panel is removed, or the encoder cover is not intact, or the optional conduit box is not installed, the drive must be installed in an enclosure with side openings less than 12. Important: For all settings except option 3, the drive must receive a leading edge from the start input for the drive to start after a stop input, loss of power or fault condition.
FusingThe ratings in the table that follows are the recommended values for use with each drive rating. All digits flashing indicates a fault condition. This setting slows down the current regulator response and attempts to correct this condition. None Switch two motor leads. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.
This example provides basic navigation instructions and illustrates how to program the first Program Group parameter. This key is always active. Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc. A Code Descriptions for Parameters A140-A147 Table E. The inputs will automatically adjust to the voltage applied and no additional drive adjustment is necessary. Verify proper configuration prior to applying input signals.
A Catalog Number Description Table B. Important: Power to drive must be cycled before any changes will affect drive operation. For additional information refer to Appendix F. When Enabled, the value held in the motor overload counter is saved at power-down and restored at power-up. Then all other positions could be setup in units of cm.
