why current drawn by stepper motor doesnt increase when load is applied on motor?
Hi all,
I am working with a ST-Nucleo board and L6470H Eval board to control a stepper motor(QSH4218-51-10-049). Using the SPIN evaluation software I gave the values for Holding current, Target current etc. But when I run the motor, the motor is drawing the current (0.6 A) without any load, and the current is not increasing when I tried to increase the load on motor, but the motor started missing the steps. Is this common with stepper motor?
Can anyone suggest me a solution.
