Allen-Bradley PowerFlex 70 Installation Instructions

Rockwell Automation Publication 20A-IN009E-EN-P - January 2015 51
PowerFlex 70 Adjustable Frequency AC Drive
OverSpeed Limit 25
➊
Functions such as Slip Compensation or
Bus Regulation have attempted to add
an output frequency adjustment greater
than the value programmed in
[Overspeed Limit].
Remove excessive load or
overhauling conditions or increase
[Overspeed Limit].
OverVoltage 5
➊
DC bus voltage exceeded maximum
value.
Monitor the AC line for high line
voltage or transient conditions.
Motor regeneration can also cause a
bus overvoltage. Extend the decel
time or install dynamic brake option.
SW OverCurrent 36
➊
Drive output current has exceeded the
1 ms current rating. This rating is greater
than the 3 second current rating and less
than the hardware overcurrent fault
level. It is typically 200…250% of the
drive continuous rating.
Check for excess load, improper DC
boost setting. DC brake volts set too
high.
