To get the best performance out of the TMC4671 it is recommended to choose an encoder which has at least 12 bit resolution and a propagation delay of less than 2μs.
The TMC4671 does not directly support an SSI encoder, but an SSI encoder can be used with the TMC4671. In order to do this, you will need to connect the SSI encoder to a microcontroller (or similar host…
The “PID_Postition_error” register in TMC4671 is a read-only register. It is used for monitoring purpose only and it is not possible to configure this register. The only way to check if the Position Error…
No we cannot use SVPWM for stepper motor while using TMC4671, SVPWM is only supported for 3 phase BLDC Motors and for stepper motors it should be turned off.
Does the TMC4671 use 2-level or 3-level PWM?
The TMC4671 implements 3-level PWM.
2-level PWM uses two distinct voltage states - positive voltage and negative voltage.
3-level PWM uses three distinct…
The feedforward feature is not directly from TMC4671. Instead it is implemented externally in Landungsbruecke MCU
it is activated by default and can be controlled by AP 52 please refer https://github…
In closed-loop configuration, the only way to reverse the direction of the motor is by giving a negative velocity. There is no software bit that can reverse the direction of the motor in a closed-loop…
With TMC4671, the best way to tune a bi-quad filter typically starts with high-frequency cutoff values, then reduce it, iteratively. Customer can use the TMCL-IDE tool to calculate the bi-quad filter parameters…
