The government data indicates the ramp has a max capacity of 600 lbs. The label supplied with the ramps sold to us states 500 lbs. Our resident gov't inspector will not release our shipment to the gov't. Do you know where the government may have gotten the 600 lb figure? PN UTW1030

That is difficult to answer as the Government is faced with a housing Crisis where foreign investors buy property and then land bank it. They do not rent out the house and they don't live in it.
then there is a lack of supply of housing and the cost of housing increases. There is talk of adding a land tax to unoccupied houses in Australia . So it might change in the future.
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?
The ramp system has a battery
monitoring system. If the battery voltage falls below 11 Vdc when the
ramp movement is initiated or the battery voltage falls below 10 Vdc
after ramp movement has been initiated, ramp movement will be stopped
and gives that error message.
The ramp will not be enabled until such time as the battery voltage
exceeds the above limits. The battery voltage must be raised to be to
correct this problem either by charging or replacing the battery.

1500Kg is more likely to be the maximum towing weight.
You should, in theory, be able to launch and recover a boat/trailer of this combined weight ok, but in practise you need to consider how slippery the ramp is and if your front wheel drive vehicle will be able to cope with it.
Use a long strop attached to the trailer and looped around the towing hitch, to launch and recover the boat, so your car stays well away from the water.
You could have some problems getting enough grip with your front wheel drive, when recovering a boat.
I have had to recover my boat from a rocky beach when I couldn't get it back to the launch ramp because of bad weather. I was very thankful that I had a four wheel drive car for that.
What ever you do, ALWAYS plan carefully exactly how you are going to do the launch or recovery and make sure you stop and think about it before doing it.
