Why is heating up L6230 chip (on IHM07M1 expansion board)

I have a Nucleo-F302R8 board with X-Nucleo-IHM07M1 motor driver.When I run the motor (using my sensorless algorithm, PWM frequency is 20kHz) the L6230 chip is started to heat up and the temperature of the chip has very fast increased.In the L6230 dat...
