Hello, we are using G2 High-Power Motor Driver 24v21 H-Bridge motor driver boards. The PWM and the DIR default input according to the specification are LOW. Are there pull down resistors on the board ? and what is the pull down resistor value ? We try to integrate with isolator board which has pull up on output. Thank you for the support.
The PWM and DIR pins are pulled low by the driver IC with a typical pull-down resistance of 115 kΩ.
Thanks for the reply. To be sure, these two signals are pulled low by the driver IC on the High-Power Motor Driver 24V21 driver board ? can you provide the driver IC part number so we are sure also. Regards.
Yes, STEP and DIR are pulled low by the driver IC.
We do not disclose the driver IC on the G2 High-Power Motor Driver boards.
