I am working on developing a board to replace the ST GS-D200S with the L6208 for a pre-existing application. I have already designed and manufactured a small amount of boards for this purpose.

I can't seem to get the proper torque out of the motor I am using (datasheet below).
The system is running at 2A and 24V. I am not sure of the driving frequency.
Also, when the motor is running correctly (although with low torque) it will intermittently seize up and make a grinding noise.
I used the suggested component values for the charge pump. My current sense resistors are .3 OHMS/2W. I have a voltage divider of 10k and 1.15k supplying the Vref's which gives a ref voltage of approx. .515.

I know this seems like very limited information but if anyone can provide any help I would greatly appreciate it.

The specific motor is the HY200 2215 0220 AX04
