How to use Revolute - Rotational Interface to connect SimElectronics motor to SimMechanics joint

I tried to rotate the revolute joint of a machine in SimMechanics. The actuator is from SimElectronics, so I use the Revolute - Rotational Interface block to connect the motor and the joint together. The whole block model is here : http://imgur.com/KII2wGA

But when I tried to run the simulation, I got the following error:

 Not enough input derivatives were provided for one or more Simulink-PS Converter blocks associated with the highlighted Solver Configuration block, for the solver chosen. Implicit solvers (ode23t, ode15s, and ode14x) typically require fewer input derivatives than explicit solvers, and local solvers never require any. You can provide more input derivatives by selecting different options (including turning input filtering on or increasing the number of user-provided input derivatives) on the Input Handling tab of Simulink-PS Converter blocks linked below:

     ...'R0x2D1000iA80F_1joint_motor/Revolute - Rotational Interface/Simulink-PS Converter' (1 required, 0 provided)

I've tried to control the machine using SimMechanics Joint Actuator, which gives a correct result. The error occurred when I tried to control it with the motor from SimElectronics.

What's the problem with the model and how to solve it? Thanks

Did you get this figured out?

That's great Tony, I have a feeling I'll be encountering a similar problem soon. If you don't mind my asking, how long have you been using Simscape and the simpackages? Do you recommend any references?

I'm just getting into this myself.
