TIDM-02010: Module over current in a 5kw PMSM drive

Part Number: TIDM-02010


We are trying to drive a 5kW PMSM through the 1.5kW HVAC drive of TI. 

We are using the same tidm-02010 and dual motor control algorithm for driving the motor. 

We have changed the motor parameters according to 5kW motor and when enabling motorVars[0] we are getting module over current fault.

The parameters of 5kW PMSM are

5kW, 200 V, 18 A, 6000 rpm, 2pole, Rs= 2ohm, Ld = 1.71mh, Lq = 1.81mH, inertia = 0.000586575. 

Kindly help us in knowing why module over current occurs. What are the parameters that lead to module over current. 

Appreciate your help asap.
