BOOST-DRV8711: Assistance Required for Stepper Driver Configuration & GUI Application

Tool/software:

Hi Team,

We are working with the DRV8711 stepper driver and the PR57HS112-4204-01-R stepper motor.

Referring to the driver chip datasheet, we have configured the motor with the following settings and an input step signal of 200 pulses/sec:

• ISGAIN: 10
• DTIME: 850 ns
• TORQUE: 100
• TOFF: 30 µs
• TBLANK: 0x80
• DECMOD: Auto mixed decay (always enabled)
• OCPTH: 500 mV
• OCPDEG: 2 µs
• TDRIVEN: 2 µs
• TDRIVEP: 2 µs
• IDRIVEN: 100 mA
• IDRIVEP: 50 mA

We observe that the motor rotates; however, there is an abnormal vibration during operation.

Additionally, we are trying to locate the BOOST-DRV8711 GUI application and its example source code for reference, but we have been unable to find them. Kindly guide us in resolving these issues.

Thanks & Regards,
Sugadev S
