Acceleration vs time data input

I have tried to input Acc vs Time data as a Motion to a translation joint. For testing i have created a cylinder and created a curve and gave a joint to the cylinder and the ground.

The curve contains Accelaration data in mm/s^2. When i solved the model, i the cylinder started to fall, not as expected from the curve. The data is 170sec recorded at 100Hz.

The cylinder keeps falling

Kindly please help me.

Thankyou.
