3. A motor driver operation On the other hand one may use a power supply of lower current rating than that of motor typically 50 70 of motor current The reason is that the driver draws current from the power supply capacitor only during the ON duration of the PWM cycle but not during OFF duration Therefore the average current withdrawn from power supply is considerably less than motor current For example 2 3A motors can be well supplied by one power supply of 4A rating Multiple drivers It is recommended to have multiple drivers to share one power supply to reduce cost provided that the supply has enough capacity DO NOT dazy chain the power supply input pin of the 5 H420 HA335 High Performance Full Half Step Driver V3 3 drivers connect them to power supply separately to avoid cross interference Higher supply voltage will allow higher motor speed to be achieved at the price of more noise and heating If the motion speed requirement is low it s better to use lower supply voltage to improve noise heating and reliability NEVER connect power and ground in the wrong it will damage the driver 5 Selecting Half Full Step and Current This driver uses an 6 bit DIP switch to set half full step and current as shown below Dynamic Current Halt Full Step Halt Full Current Half Full Step Selection The 6 bit of DIP switch determine driver s working mode When the switch set to be OFF it is HALF step wor
