We have four Pololu Jrk G2 18v19 motor controllers controlled via I2C by a Arduino Nano 33 BLE for four brushless DC motors. We are testing the controllers without motors connected at the moment. One of the motor controllers reports current draw when a target is set, even though no motor/device is connected to OUTA and OUTB, as shown in the screenshot below:
This occurs when driven via the configuration utility as well as by I2C. For reference, here is the output of our UI (controlling via I2C) showing the other motor controllers reporting 0 mA current draw:
Is this behavior expected?
Thank you for your support.
