Limit the pressure supplied to the inlet of the motor, plug the return port. Place the case drain line into a bucket, or install a case drain line if not equiped and comparte the flow to the manufacturers specs. I don't know what they are off hand, but shouldn't be more than 1 gpm I wouldn't think. Another quick test is if you can turn the bare shaft easily with no resistance when both fluid ports are open, the geroller set has quite a bit of wear. This quick test doesn't work in some applications such as wheel motors as they are sometimes ordered as "free running" motors. They are the same motor, but with a looser fitting geroller set.

Danfoss FC202 VLT Start-up problem


I didn't see what these drive application was for. Is it for a fan or pump?
I assume you've entered all the motor data, FLA, RPM Voltage, KW etc. If you have three of these you must have experience with these drives. I've only used these drives on fans, and once on a pump.
Have you tried the Automatic Motor Adaptation ? (AMA) Have you programmed the PID start speed? Read the note about this feature as I think you have to have min speed set at 0 .I know you said you tried changing the ramp up time. If this is on a pump, the ramp up time may be too slow causing the motor to draw too much current when it's pumping way down on the pump curve. People would have a tendancy to make the ramp up time loonger, to make the load easier to start, however the torque requirement on a slower speed could be so high, the motor is overloading. I'd like to know what you find out, pleas post your solution. Have you contacted Danfoss or your local rep?

I have a sundstrand pump, model 15-2078. It has 4 ports, I know the 2 that go to the hyd. motor. I am not sure which one is the suction and which one is the return


The suction is at the front of the pump by the input shaft. The inlet can be set up as RH or LH by simply moving the plug to the other side.

The case drain is at the back of the pump housing between the 2 ports on the end cap that go to the hydraulic motor. There are 2 case ports 180 degrees from each other.

This is now handled by Hydro-Gear. www.hydro-gear.com.

Charge pressure drops to zero when hot and grouls.Where is the charge pressure set? Jack


What is the model number and brand of your pump? Your description is a classic statement when hydros (your pump and motor) are failing. You can try charge pressure adj to make it work better. Model number will tell me where to direct you.

It sounds like your hydrostat pump and motor are failing (leaking too much). Seals will not fix this problem. Send me your model numbers for verification and further info.
