Hello,
we want to replace a stepper motor with a BLDC motor for a pump and would like to use your driver for this. However, the problem is that the start-up does not work with the hose installed. I have therefore removed the hose for the MPET and would now like to adjust the parameters manually, but I can't get any further. The start-up simply does not work with the hose installed. The starting torque probably needs to be increased, but which parameters do I need to adjust?
The motor should have sufficient power. The stepper motor needed about 22W to start up, the new motor has 31W power.
Wen observing the algorithm state, it mostly fails at state MOTOR_CLOSED_LOOP_UNALIGNED but the pump head never turns more than ~2-3°.
