How to resolve SW OverCurrent on Allen-Bradley PowerFlex 70?
To address a SW OverCurrent issue on your Allen-Bradley Controller, check for excess load, improper DC boost setting, and ensure the DC brake volts are not set too high.
What to do if auto-reset run fault occurs on Allen-Bradley DC Drives?
When an auto-reset run fault occurs and [Auto Rstrt Tries] is set above “0,” the [Auto Rstrt Delay] timer starts. The drive will attempt to automatically reset the fault when this timer reaches zero. If the initial fault condition is no longer present when the timer expires, the fault resets and the drive restarts, provided the drive remains in Run state. If a Stop is initiated, the Restart function is aborted.
Are there non-configurable alarms on Allen-Bradley DC Drives, and what does it mean?
Yes, non-configurable alarms exist on Allen-Bradley DC Drives. These alarms are always enabled.
Are there user configurable alarms on Allen-Bradley DC Drives, and how to use them?
Yes, there are user configurable alarms on Allen-Bradley DC Drives. These alarms can be enabled or disabled using [Alarm Config 1].
What to do if Allen-Bradley PowerFlex 70 Controller shows DB Resistance?
If your Allen-Bradley Controller indicates a DB Resistance problem, replace the resistor.
How to troubleshoot Analog In Loss on Allen-Bradley Controller?
To troubleshoot an analog input loss on your Allen-Bradley Controller: * Check the parameters. * Check for broken or loose connections at the inputs.
How to resolve Port 1-6 Adapter issues on Allen-Bradley PowerFlex 70 Controller?
To resolve issues with the Port 1-6 Adapter on your Allen-Bradley Controller: * Check the communication adapter board for proper connection to the external network. * Check the external wiring to the adapter on the port. * Verify any external network faults.
What to do if Allen-Bradley PowerFlex 70 Controller shows Pwr Brd Chksum1?
If your Allen-Bradley Controller displays a Pwr Brd Chksum1 error: * Cycle power to the drive. * If the problem persists, replace the drive.
How to troubleshoot Decel Inhibit on Allen-Bradley PowerFlex 70?
To troubleshoot a Decel Inhibit issue on your Allen-Bradley Controller: * Verify the input voltage is within the drive's specified limits. * Confirm the system ground impedance follows proper grounding techniques. * Disable bus regulation and/or add a dynamic brake resistor and/or extend the deceleration time.
How to troubleshoot HW OverCurrent on Allen-Bradley PowerFlex 70?
To troubleshoot a HW OverCurrent issue on your Allen-Bradley Controller, check the programming, look for excess load, verify the DC boost setting, and ensure the DC brake volts are not set too high. Also, investigate other potential causes of excess current.
