The present disclosure provides a method for controlling driving of a motor by a Programmable Logic Controller (PLC). In one embodiment, the method includes: upon an initiation of an N-th position determination control period, stopping a scan program being executed; receiving one or more motor driving commands for one or more axes during a preset position control processing region; calculating one or more axis-based motor movement amounts corresponding to the one or more motor driving commands for the one or more axes during a preset position control calculation region; resuming execution of the scan program; and upon an initiation of a (N+1)-th position determination control period, driving the motor based on the one or more axis-based motor movement amounts calculated during the position control calculation region.
