PRODUCTION DATA
In this application, a 1.5 A rated stepper motor used in printers was subjected to load torque transients and the motor speed was simultaneously changed, to mimic the conditions for a typical printer.
Figure 3-11 and Figure 3-12 showcase the output current and supply current waveforms with and without auto-torque.
