Other Parts Discussed in Thread: CSD18532Q5B, DRV8323,
Hello experts,
I have a custom motor control board with a DRV8353RSRGZR driver to control a 57BLR70-24-02 motor in order to lift up different weight.
When the load is under 160N the motor can lift it up with no problem (example: supplied with 10%PWM, the motor can lift a 120N load up) and the motor phase looks like this
But whenever I try to lift up heavier loads like 160N, 200N etc.. even setting up more PWM duty cycle, the driver nFault pin is asserted low and the VDS_HB and VDS_LC are set in the Fault Register 1.
Here are phase currents shown when the motor is stalled and before I disable the driver to check for Fault Registers
1V = 1A
I don't understand this behaviour.
I can provide
SPI config :
Register => Config
0x02 => 0x41
0x03 => 0x3EF
0x04 => 0x7EF
0x05 => 0x364
0x06 => 0x243
0x07 => 0x0
