What to do if my Vexta aStep AS motor does not run?

  If the Vexta DC Drives motor isn't running, several issues could be the cause: * Check for bad connections for CW or CCW input by reviewing the connections of the controller and driver, and verifying the voltage and width specifications for the input pulse. * In 2-pulse input mode, if both CW and CCW pulse inputs are 'ON' simultaneously, input the pulse signal to either the CW or CCW input, ensuring the terminal with no input is set to 'OFF'. * In 1-pulse input mode, if the pulse signal is connected to the DIR input, connect it to the PLS input instead. * If it is an electromagnetic brake type, turn the power on to release the electromagnetic brake.
