What to do if Allen-Bradley Controller shows Motor Overload?
If the Allen-Bradley Controller displays a 'Motor Overload' message, it indicates that the motor load is excessive. Reduce the load to ensure the drive output current does not exceed the current set by [Motor NP FLA].
Why does my Allen-Bradley powerflex 700 show OverVoltage?
The Allen-Bradley Controller might show an 'OverVoltage' error due to high AC line voltage or transient conditions. It can also be caused by motor regeneration. To address this, monitor the AC line, extend the deceleration time, or install a dynamic brake option.
What causes HW OverCurrent in Allen-Bradley powerflex 700 Controller and how to fix it?
The 'HW OverCurrent' error in your Allen-Bradley Controller can be caused by programming issues, excessive load, an improper DC boost setting, or DC brake volts set too high, among other factors leading to excess current. Check these settings and conditions to resolve the issue.
What causes SW OverCurrent in Allen-Bradley Controller?
The 'SW OverCurrent' in Allen-Bradley Controller can be triggered by excess load, an improper DC boost setting, or excessively high DC brake volts. Check these settings.
How to fix OverSpeed Limit on Allen-Bradley Controller?
To resolve an 'OverSpeed Limit' issue on your Allen-Bradley Controller, remove any excessive load or overhauling conditions. Alternatively, increase the [Overspeed Limit] parameter.
How to fix FluxAmpsRef Rang error on Allen-Bradley Controller?
To fix the 'FluxAmpsRef Rang' error on your Allen-Bradley Controller: 1. Reprogram [Motor NP FLA] with the correct motor nameplate value. 2. Repeat Autotune.
What to do for Decel Inhibit on Allen-Bradley powerflex 700 Controller?
To address 'Decel Inhibit' on an Allen-Bradley Controller: 1. Verify the input voltage is within the drive's specified limits. 2. Ensure the system ground impedance follows proper grounding techniques. 3. Disable bus regulation, add a dynamic brake resistor, or extend the deceleration time. 4. Disable the function with parameter 238.
What does TB Man Ref Cflct mean on Allen-Bradley powerflex 700 Controller?
The 'TB Man Ref Cflct' error on the Allen-Bradley Controller occurs when “Auto/Manual” is selected (default) for [Digital In3 Sel], parameter 363 and [TB Man Ref Sel], parameter 96 has been reprogrammed, meaning no other use for the selected analog input can be programmed. You can resolve this by either verifying/reprogramming the parameters that reference an analog input or reprogramming [Digital In3] to another function or “Unused.”
