TMC2100-TA Frequently Asked Questions (FAQs)
The recommended PCB layout for the TMC2100-TA is to keep the analog and digital grounds separate, use a solid ground plane, and keep the sensitive analog signals away from the digital signals. A 4-layer PCB with a dedicated power plane is also recommended.
To optimize the performance of the TMC2100-TA in a noisy environment, use a low-pass filter on the input signals, add decoupling capacitors on the power supply lines, and use a shielded cable for the motor connections. Additionally, consider using a common-mode choke on the motor lines to reduce electromagnetic interference (EMI).
The TMC2100-TA can handle a maximum motor current of 2.8A peak, but it's recommended to derate the current to 2A peak for continuous operation to ensure reliable operation and prevent overheating.
To configure the TMC2100-TA for microstepping mode, set the M0, M1, and M2 pins according to the desired microstepping resolution (e.g., 1/16, 1/32, or 1/64). Additionally, set the STEP pin to the desired frequency and adjust the VREF pin to set the current limit.
The VREF pin on the TMC2100-TA sets the current limit for the motor. The current limit is proportional to the voltage on the VREF pin, and it's used to prevent overheating and damage to the motor or driver.
