Hi, everyone, I bought 2 tic36v4 and I’m trying to configure it so it works properly with my stepper motors.
I used this nema 23 and this other nema 23 both of 4.2 Amps, so I set the TIC current limit to 4297mA and use refrigeration. I powered the motors with a 48V 32A power supply that I happen to have.
The first one (SCA5618M4204-A) has 1.8mH, and 0.5 Ohms per wiring, and 140 Ncm of holding torque.
The second one (SCA5618L4204-B) has 2.1mH, and 0.55 Ohms per wiring, and 230 Ncm of holding torque.
I perform several tests of the holding torque of each motor to be sure that the driver drives them properly but neither reaches the values specified by the datasheet.
Then I tried a different configuration, and finally, find that the motor respects their specified holding torque when I configure the driver with a “Slow Decay Mode” and 15us for the “Fixed off time”.
The problem is that when I use the Slow decay mode and micro-stepping (like 1/8 or 1/16) then the steps behave weird, like shorter or weak steps and then one stronger. If I use a decay mode different from Slow the motor will lose its torque.
So, my question is how I have to configure the driver so my motors respect their datasheet?.
I upload my settings.
