Hello,
I have several plastic-sleeved roller conveyors in series, all driven by the AB PF525's. Most of the conveyors are straight, except for the most downstream - declined. They run rubber material back-to-back which have some spring-back/bounce when the motors go turn on\off.
I keep seeing the following faults sporadically:
-F5 - Overvoltage
-F4 - Undervoltage
-F73 - EN Comm Loss (drives are Ethernet connected to PLC5000 through a switch)
Due to the spring back of material, the stop-mode=coast,CF. No break resistors. Accel Time=5s.
I enabled the FlyStart P545 with the 65% current match for the P546, but that hasn't made a difference.
My theory is I get F5:
-spring-back generates back EMF
-start command is sent when the material is in the process of the spring-back
Motor: 1HP 460VAC
VFD: AB525 25B-D2P3N104 - 1HP
Any suggestions?
