CCS/DRV8303: DRV8303 + InstaSpin, when restarts motor drive

Part Number: DRV8303

Tool/software: Code Composer Studio

Hello,

I would like to ask about InstaSpin and DRV8303,handling En_Gate signal of DRV8303.

For example,InstaSpin lab 5b,

I tried to stop motor by these steps:

1.flag "gMotorVars.enable_Sys" set to 0.

2.set En_Gate signal of DRV8303 to low.

And, restarts motor drive by these steps:

1.set En_Gate signal of DRV8303 to high.

2.flag "gMotorVars.enable_Sys" set to 1.

When I restarted the motor drive, DRV8303 overcurrent error occured.

The Drv8303 overcurrent error doesn't occur ,if I doesn't set En_Gate to low when stopping motor.

I would like to know the things to keep in mind about restarts the motor driving,set En_Gate from low to high.
