Hi,
I’m hopping someone could help.
The hydraulic motor is controled by a high-performence valve named D1FPE50MA9NS00. The valve is controled by RMC75S. When the hydraulic motor speed is 3301rpm,The system tend to oscillate. if the speed is not at 3301,the system don’t tend to oscillate. only at 3301rpm.
What could I do?
Thank you.

Can you save and send two plots to Delta support?

  • One plot at a normal speed, when the system is not oscillating.
  • One plot at 3301 rpm when the system is oscillating.

If you can send those to support@deltamotion.com our engineers should be able to figure out what the system is doing at that special rpm.
